Angikabeki lutho lwe Bash, futhi ngukuthi ngenkathi ngingena ezweni elihle lePython ngikhohliwe okuncane ngalo omunye umngani ongisize kakhulu 🙂
Lapha ngifaka okuthile kubathandi beBash, njengoba isihloko sisho ... Ngizokukhombisa ukuthi ungabheka kanjani ukuthi ngabe kukhona ifayili noma ifolda kuhlelo, usebenzisa nje: if
Sizokwakha ifayela le- .sh bese silinika izimvume zokwenza lokhu, ngoba vele ubeke umyalo olandelayo ku-terminal:
thinta test.sh && chmod + x test.sh
Lokhu akwenzile ukudala ifayela (thinta test.sh) futhi ngikunikeze nezimvume zokwenza (chmod + x test.sh)
Ngemuva kwalokho ake sibhale okulandelayo kuyo:
if [ -d /opt/ ];
then
echo "Sí, sí existe."
else
echo "No, no existe"
fi
Kwenzani lokhu?
Okulula 😀
Kumugqa wokuqala - » uma [-d / opt /];
Lapha sibuza, ngabe / opt / isiqondisi sikhona? Yebo isiqondisi / ifolda, ngoba -d kusho umkhombandlela noma ifolda.
Lapho-ke uma kwenzeka sikhona sizophrinta esigungwini «Yebo ikhona.»(Lo ulayini 2 no-3)
Ngaphandle kwalokho futhi / opt / ayikho, khona-ke sizophrinta «Cha ayikho»(Imigqa 4 no-5)
Ngemuva kwalokho emgqeni wokugcina (inombolo 6) sivala i-if futhi yilokho.
Yenza isivivinyo, kuzokukhombisa ukuthi / opt / is exist.
Uma ufuna ngikukhombise omunye umbhalo (lowo ongekho) shintsha / khetha / nganoma iyiphi enye ifolda engekho kusistimu yakho, ngokwesibonelo: / asd /
Njengoba ukwazi ukubona, -d isisiza ukuthi sazi ukuthi isiqondisi sikhona yini, manje manje uma siguqula -d to -f ukubheka ukuthi kukhona amafayela (-d = isiqondisi, -f = ifayela / ifayela)
Isibonelo:
if [ -f /etc/hosts ];
then
echo "Sí, sí existe."
else
echo "No, no existe"
fi
Nalu uhlu lwezinketho:
-d - »Bheka ukuthi kukhona umkhombandlela othile
-f - »Bheka ukuthi ngabe ikhona ifayili elikhona
-w - »Bheka ukuthi ngabe ifayili elithile linezimvume zokubhala
-x - »Bheka ukuthi ngabe ifayili elithile linezimvume zokusebenzisa.
Futhi akukho okunye okuningi ongangeza u-🙂
Ngiyazi ukuthi lokhu kuzoba wusizo kakhulu futhi kuthakazelise kulabo abathanda ukuhlela eBash 😉
Phendula ngokucaphuna
Enye indlela yokukwenza ngaphandle kwe- if… ke..else:
test -f /etc/hosts && elcomandoNoma futhi
test ! -f /etc/hosts && echo "no se encontró el archivo"Njll
Ngakwesokudla 😀
… O_O… UnguHugo, uHugo waseCuba? … Isebenzisa iWindows8, WTF !!!
Yebo, ngiyajwayela le OS futhi uma kufanele ngikhulume ngokungagwegwesi, ukuphela kwento engithole ukuthi ilusizo ngumphathi wamakhophi, ngaphandle kwalokho mina ngokwami ngikuthola kubuhlungu, ikakhulukazi isikhombimsebenzisi sayo se-hybridi nezinhlelo zokusebenza zemetro. Ngiyithanda ngaphansi kwe-Vista ne-7 (yize isebenza kahle kakhulu kunalezi), engingayithandanga nami. Ukuphela kwento engiyisebenzisela yona ukudlala i-NFS13 ne-Skyrim, kepha le OS ithatha isikhala esiningi kangangoba bekufanele ngisuse ukwahlukanisa kwami kwe-Linux [snif].
Kodwa-ke, ukuze ube nokuthula kwengqondo, ngizokutshela ukuthi ngayizolo ngilande i-Arch ISO kaJanuwari futhi ngihlela ukuyivivinya kancane kunguqulo yayo ye-x86-64, lapho nje sengithola i-repo (uzothanda unayo?). Manje njengoba ngibonile ukuthi isebenzisa amaphakheji asayiniwe ngokuzenzakalela, kunginikeza ukuzethemba okukhulu kokuntywila.
Futhi ubaba wangitshela nokuthi uzongithumelela i-Sony Xperia, engifuna ukuyisebenzisa ngokunenzuzo yokufunda izinhlelo ze-Android, obekuyisifiso esilindile. Ngakho-ke yehlisa umoya, angikayi engxenyeni emnyama yamandla, buahahahaha 😉

Wenas! ..
Singayenza efanayo .. .. kepha isiqondisi sidluliswe njengepharamitha ..
if [ -d $1 ];then
echo "Sí, sí existe."
else
echo "No, no existe"
fi
Futhi sikubiza ngokuthi:
./test.sh / opt /
Ukubingelela ..
UMA kungewona umjikelezo xD
Ingifanela njengegilavu yesikripthi engisenzayo. Ingabe kuvumelekile ukusebenzisa amakhadi wasendle? Isibonelo, ukuthola ukuthi kukhona yini ama-.mp4s bese usebenzisa okuthile kuwo.
uma [-f * .mp4];
...
Yebo, kusebenza ngokuphelele ..
Ngisho ngamapharamitha .. "* .mp4"
Isibonelo,
if [ -f $1 ];
then
rm -r $1
else
ls
fi
Uma uyibiza: ./test.sh * .mp4
Uma ithola amafayela we-.mp4 iyawasusa .. ..kodwa ayiwabhalisi amafayela akuleyo nkomba ..
Siyabonga ngempendulo namathiphu! 🙂
Uphuthelwe i-f xD
rm -rf $ 1
Lokhu kujabulisa ngokwengeziwe!
Wonderful !!!, Nsuku zonke ngiyithanda kakhulu iLinux, iWindows ibuyiselwe ekhoneni elimnyama leHard Drive yami, esesizosuswa ukuze kukhanyiswe iLinux.
Kuhle! .. ..bese thatha isinyathelo esilandelayo .. bese uyakhipha ..
Izinyanga eziyi-6 ezedlule cishe. Ngine-GNU / Linux kuphela kuyo yonke imishini yami futhi angidingi enye .. .. hhayi i-W $ .. noma iwayini .. .. futhi ngijabule kakhulu kanjalo .. 😉
Futhi ngithelela indawo engizungezile .. njengoba wonke umuntu engibona ngine-Arch yami, ngiyashesha, ngisebenza kahle futhi ngijabule .. .. futhi bangicela ukuthi ngifake i-Linux .. ..yeah! .. 😀
Ungahlola futhi izandiso ezahlukahlukene, ungasebenzisa into efana nayo
#! / bin / bash
Uhla lwemibhalo = $ IKHAYA / Ukulanda
uma [$ Directory]; lapho-ke
echo "Nalu Uhlu Lwezinhlobo Zamafayela:"
echo "mp1, mp2, mp3, mp4, wav, flac, flaad, aud, midi"
ls {* .mp ?, *. wav, *. fla, *. aud * .midi}
fi
ukusebenzisa {} kukuvumela ukuthi ucacise izandiso eziningi kuleli cala, ukusetshenziswa kwe - "?" , yikhadi lasendle, elikuvumela ukuthi uthathe "Noma yisiphi Isici"
Ngiyethemba kuyakusiza

@KZ, tshela okuningi ngalokhu: "futhi lokho kungenxa yokuthi ngingena ezweni elihle lePython"!
HAHAHAHA nah ... kancane kancane 🙂
Ngisengu-newbie ePython, anginaso isikhathi sokunikela ngamahora namahora kuso, ngakho-ke ngiyahamba kancane yebo, ngiyahamba kodwa ngiqinisekile ekufundeni kwami 😀
Ngiyabonga kakhulu 😀 izolo nje bengicabanga ukuthi ngingenza kanjani lokhu.
lokhu nge-ncurses kuhle 🙂
ngegama elingu-1… NGOKUPHELELE!
Isikhathi eside bengiphelelisa iskripthi sokwenza okulandwayo kusuka kwi-Intanethi, kepha bengibhekene nenkinga yokuthi ilande amafayela ebiwacele i-1 kaninginingi ngaphandle kokukwazi ukuqinisekisa ubukhona be-1ro.
I-tuto enhle kakhulu.
Umnikelo omkhulu, lapha ovela eChile uyawuthokozela.

hlola ukuthi ngabe ifayela livela enkombeni
Uma ngifuna ukubheka ukuthi kukhona noma yiliphi ifayela elisendleleni ethi «/ tmp / receivers», ngikhiphe noma yimuphi umyalo, kungaba kanjani?
Ngizojabula kakhulu
Phendula ngokucaphuna
Sawubona, futhi unqume nge-IF ukuthi ngabe ifayili ligcwele ngokuphelele ???. Ngikubuza lokhu ngoba uma ugcwalisa ifayili lokudluliswa, lingayithatha noma yingxenye yedatha.
Ukubingelela nokubonga ngempendulo yakho.
Ngicabanga ukuthi kufanele futhi ungeze isibonelo, esifana nokuthi "Bheka ukuthi ayikho yini" ifayili "noma" umkhombandlela "njengesibonelo
ukubheka ukuthi ayikho, ngokwesibonelo sebenzisa okuguquguqukayo->

Sanibonani KZKG ^ Gaara umbuzo wokuthi ngingenza kanjani ukusebenzisa i-curl. Ngingathanda ukwazi ukuthi ngingayifaka kanjani i-url kusuka kukhonsoli ukubona ukuthi iyatholakala yini ngokwesibonelo http://portal.com/directorio/archivo1.php Lapho i-file1 izogcina khona ama-IPs wokuvakasha, kungenxa yokuqapha iqembu engidinga ukulifaka lelo phini njalo uhhafu wehora ukuze ngazi i-IP yomphakathi ngoba iyashintsha ngezikhathi ezithile futhi angikwazi ukuxhuma nge-ssh .
Ngiyabingelela ngiyabonga kusengaphambili uNkulunkulu akubusise.
Sawubona, ungubani?
Okokuqala, kufanele usho ukuthi ukuguquguquka kwe-IP (ngokwesibonelo) okuqukethwe yilelo fayela, kulokhu kufanele:
1. Landa ifayela
2. Buka okuqukethwe kwayo bese uthola i-IP lapho
3. Leyo IP iyahluka
Isibonelo:
Lapha silanda ifayela - »wget http://portal.com/directorio/archivo1.php -o ifayela.html
Ngemuva kwalokho sabela okuqukethwe okuguquguqukayo: - »: $ {IP: =` cat file.html`}
.. uthatha ukuthi okuqukethwe kwalelo fayela kune-IP kuphela, uma kungenjalo, kuzofanele usebenze nge-grep, awk noma ikhanda.
Lapho usunayo i-IP njengokuguquguquka, konke okunye kuyinto elula kunazo zonke emhlabeni 🙂
Uma ufuna, ngibhalele nge-imeyili (kzkggaara[at]desdelinux[ichashazi] inethi) Ngizokusiza ngenjabulo
Ngiyabonga kakhulu kzkggaara ngiyabonga kakhulu.
Sawubona, angiqondi okuningi ngekhompyutha futhi angazi ukuthi lokhu okuthunyelwe kuhlobene yini nenkinga enginayo.
Ngiphawula uma kungenzeka ungifunde, noma ngabe okuthunyelwe kuvela onyakeni owedlule:
Kuvela ukuthi ngakha ifolda kudeskithophu yami ukugcina amanye amavidiyo. Ngisusile lawo mavidiyo ngoba bengingasawadingi futhi manje le folda ingitshela ukuthi ayikho (noma ibonakala kudeskithophu yami).
- Leyo yinkinga yokuqala enginayo:
Angikwazi ukususa ifolda.
- Inkinga yesibili futhi ngicabanga ukuthi ibaluleke kakhulu:
Emzameni wokususa ifolda, ngafaka ifolda ye-PHOTOS. Manje lapho ngivula ifolda "engekho" ayinalutho futhi IZITHOMBE azikho.
Ngingabuyisa kanjani izithombe? Nginike inketho ngaphakathi kwefolda ethi "Bonisa imibhalo efihliwe" kepha ifolda ye-PHOTOS ayiveli.
Ngiyethemba ungazi ukuthi ixazululwa kanjani.
Ngiyabonga
Kukhona abasebenzisi ababili okuyibo okuyinhloko: impande ne-your_user (isibonelo natalia). Bobabili banamafolda abo. your_user in / home and root in / (impande lwemibhalo). Ngokuchofoza kwesokudla kufolda bona ukuthi ekabani. Uma kuyimpande nomphathi wakho wefayela usebenzisa iSudo noma i-gksu noma i-kdesu ngokuya ngemvelo oyisebenzisayo iya enkombeni yezimpande -> impande -> Ideskithophu futhi uzothola izithombe futhi ungasusa ifolda. Amanye ama-distros uma ungeyena umnikazi wefayela noma umkhombandlela futhi ungenazo izimvume zokufinyelela akutshela ukuthi umkhombandlela / ifayela alikho. Uma ungumnikazi futhi ungeyona impande, yenza okufanayo nomphathi wefayela ngeSudo, njll bese uya enkombeni yezimpande -> / home -> personal_folder -> Desktop bese ubona ukuthi izithombe zikhona nokuthi ungayisusa ifolda.
Uma lokhu kungasebenzi, kuzofanele ubone ezinye izinketho kusuka ku-terminal (console).
Sawubona, unjani? Ngenza umsebenzi ku-bash futhi ngifisa ukwazi ukuthi ngingaqinisekisa kanjani uma kukhona umkhombandlela ofakwe kusuka kukhibhodi, ngokwesibonelo
#! / bin / bash
funda umzila
#Ngena ~ / Ideskithophu
#Ngibe sengizama ukuzulazula kulowo mkhombandlela
cd $ indlela
# Ngithola lo mlayezo we-bash olandelayo: cd: ~ / Desktop: Ifayela noma umkhombandlela awukho
Umbuzo wami uthi, yini engingayenza ukuze ngiyifake kusuka kukhibhodi ngiyithathe njengesiqondisi sendlela?
Futhi ngingazi kanjani ukuthi iqembu likhona,
kuhle nginenkinga ku-canaima yami lapho ngicindezela inkinobho cunaguaro ithi alikho ifayili noma umkhombandlela njengoba kungenza ukuxazulula leyo nkinga futhi okunye akuvuli i-cunaguaro ngicela ukubonga.
Wenza kanjani i- if in BASH uma igama lefayela linezikhala?
Isibonelo:
Idatha ka-Ephreli
Ukubuza ukuthi ngabe ifayili likhona yini
UCarlos, kanjena:
uma [["$ variable" == Idatha \ inyanga \ ka- \ Ephreli.xlsx]]; bese unanela 'ukufanisa'; fi
Futhi unga:
uma [["$ variable" == 'Idatha yenyanga ka-Ephreli.xlsx']]; bese unanela 'ukufanisa'; fi
Enye indlela:
[["$ Variable" == 'Idatha yenyanga ka-Ephreli.xlsx']] && echo 'okufanayo' || i-echo 'ayifani'
Kwezinye izindawo ezimnyama ze-intanethi bancoma ukusebenzisa [[]] esikhundleni se [], futhi uma uzoqhathanisa izinombolo lapho: ((variable> = 3)) && echo 'variable is greater than or equal to 3' || ukuguquguquka kwe-echo 'kungaphansi kuka-3'
Ngakho-ke, ngezinombolo:
uma ((inombolo! = 4)); bese unanela u - "$ {number} akayona engu-4"; enye i-echo "$ {number} ingu-4"; fi
ungayenza kanjani ikhodi ukuze iqinisekise uma umkhombandlela unombhalo othile, ukuze ukwazi ukuwuhlela.
isibonelo:
uma (umbhalo1)
ungenzi lutho
futhi
shintsha umbhalo1 ube umbhalo2
umbuzo, kungaba kanjani ukubheka yonke imizuzwana engu-15 uma ngabe ifayili likhona noma cha, ngiyabonga.
Sawubona,
lokhu:
uma [-w / home / Komun / Logs / ti]; lapho-ke
Thola ukuthi ngabe ifayela liyabhalwa yini. Kepha kusekelwe kuzimvume zomsebenzisi. Ngabe kungenziwa ukuthola ukuthi iqembu noma amanye anazo yini izimvume?
