Bash (Iqokobhe leBourne-Kwakhona) Luhlobo lweskripthi somyalelo wokutolika kwilayini. Oku Iqokobhe le-Unix eliyinxalenye yeprojekthi ye-GNU Isekwe kwiqokobhe leBourne (bsh okanye ngokulula sh kwiinguqulelo ezininzi zeUNIX).
Bash izisa uphuculo oluninzi, kubandakanya iqokobhe le-Korn (ksh) kunye no-C iqokobhe (csh). I-Bash isoftware yasimahla ekhutshwe phantsi kwelayisenisi yeGPL.
Esi sisiguquleli esingagqibekanga kwiinkqubo ezininzi zasimahla ze Unix, ngakumbi iinkqubo ze-GNU / Linux. Ikwayigobolondo emiselweyo ye-Mac OS X. Iprojekthi yeCygwin iyizisile kwiWindows okokuqala kwaye kuyo Windows 10 lukhetho lwenkqubo yokusebenza.
I-Bash ngumiliselo olupheleleyo lwe-POSIX yeenkcukacha zegobolondo, kodwa ngokuhlelwa komgca wokuyalela kunye nolawulo lomsebenzi kulwakhiwo oluyixhasayo, imisebenzi ye-csh, kunye nezinye izinto.
Inguqulelo entsha yeBhash
Kwiintsuku ezimbalwa ezidlulileyo, iqela elilawula uphuhliso lweBash lenze isibhengezo sobukho bokuqala koluntu ngokusungulwa kweBash 5.0, Inguqulelo yesihlanu ephambili yeqokobhe le Unix elivela kwiprojekthi ye-GNU.
Le nguqulo ilungisa ezininzi iibugs ezinkulu kwi-bash-4.4 kwaye yazisa ngeempawu ezintsha.
Kumyalezo ovela kuluhlu lweposi yeProjekthi ye-GNU, uChet Ramey, Umphathi weBash ucacisa ukuba ezona zilungiso zibaluleke kakhulu kukuhlaziywa kwesisombululo sokutshintsha kwe-nameref kunye noluhlu lweebugs ezigcweleyo ezifunyenwe ngokubhabha.
Iindaba eziphambili
Ezona mpawu zintsha zibalulekileyo zibandakanya izinto ezahlukeneyo zeShell ezinje nge BASH_ARGV0, EPOCHSECONDS, kunye NE-EPOCHREALTIME.
Ezi zimbini zokugqibela ziyafana ukufumana inani lemizuzwana okoko i-Epoch Unix (i-Epoch Unix), umahluko kuphela kukuba i-EPOCHREALTIME yindawo edadayo kunye ne-granularity ye-microseconds.
Qaphela ukuba i-Epoch imele umhla wokuqala apho iinkqubo zokusebenza zilinganisela ixesha.
Kukho ifayile emiselweyo esandula ukucwangciswa.h kwiBhash 5.0, evumela iqokobhe ukuba lisebenzise ixabiso le-static kwi-PATH.
Le nguqulo intsha yeBash 5.0 Ikwanokhetho lweqokobhe elitsha elinokwenza kwaye likhubaze ukuthumela kwelog kwi-syslog ngexesha lokubaleka.
Ngolwazi, i-syslog yiprotocol echaza inkonzo yelog yomsitho yenkqubo yekhompyuter. Ikwabhekisa kwigama lefomathi evumela olu tshintshiselwano.
Entre Olunye utshintsho olukhulu kule Bhash 5.0 intsha ikhuphe ukhetho iglobasciirange ngoku yenziwe ngokungagqibekanga, kodwa unokukhubazeka ngokungagqibekanga ngexesha lokuseta.
Imowudi ye-POSIX ngoku inokuvumela ukhetho tshintsha_verbose kunye nokukhethwa kwe imbali Eyakhelwe-ngaphakathi kwiBash 5.0 ukuba ngoku ungasusa uluhlu lokufaka kwimbali usebenzisa Isiphelo sokuqalisa.
Olunye utshintsho
Kukho iinguqu ezingahambelaniyo phakathi kwe-bash-4.4 kunye ne-bash-5.0. Ngokuka-Chet Ramey, utshintsho kwindlela yokusombulula izinto eziguquguqukayo zithetha ukuba ezinye izinto ezisetyenziswayo ziya kuziphatha ngokwahlukileyo, nangona bezamile ukunciphisa imiba yokuhambelana.
Ngamafutshane, I-Bash 5.0 iqulethe izilungiso ezininzi xa kuthelekiswa neBash 4.4, kodwa kunye nenani leempawu ezintsha kunye nezixhasi zokuthobela ngcono imigaqo yePOSIX. Ngolwazi olupheleleyo kwi-bash 5.0, ungabhekisa kubo amanqaku akhululwe ngokusemthethweni.
Ezi zinto zintsha kunye nezixhasi ngokuqinisekileyo zivumela iBash ukuba ikhule ngakumbi kunangaphambili.
Masingalibali ukuba uluhlu lweqokobhe lusandisiwe nje ngePowerShell Core, uhlelo oluvulekileyo lomthombo wePowerShell ebaleka kwiLinux, macOS, nakwiWindows.
Le projekthi isaphuhlisweni olupheleleyo, kodwa sinokulindela ukuba ikhule ngokukhawuleza, njengoko iMicrosoft inika ithuba lokuvula imithombo "ubuncinci okwangoku."
Uyifumana njani iBash 5.0 kwiLinux?
Ngelo xesha Kuhleli kuphela ukulinda le nguqulo intsha yaseBash ukuba ifakwe ngaphakathi koovimba bokunikezelwa kweLinux, kuba lolona khetho lulungileyo.
Ukuba ufuna ukwazi okungakumbi kwaye nabo bafuna ukufumana le nguqulo intsha ngoku, ungatyelela eli khonkco lilandelayo.
