Bheka ukuthi ngabe iyi-IP elungile noma cha eBash (umsebenzi wokuqinisekisa i-IP)

Lesi ngesinye iseluleko esingasisiza ezimeni ezithile. Lokhu ngikwenza kakhulu njengesikhumbuzo, ngoba ngiyazi ukuthi ngizokudinga lokhu futhi lapho hahaha.

Lapho senza umbhalo othile ku bash, futhi umsebenzisi kufanele afake ikheli le-IP, ukuze kamuva (iskripthi) senze okuthile sisebenzisa lelo kheli le-IP, uyazi ukuthi konke kungonakala kuphi? ... ukuthi umsebenzisi AKAYIFAKI i-IP, ukubeka noma imuphi umbhedo noma i-IP engaphelele noma into enjalo, labo abahlelayo bazi ukuthi ngiqonde ukuthini ... ngoba kufanele ihlelwe icabange ukuthi ngisho okungenangqondo okukhulu kuzokwenzeka O_O.

Ngokuqondile ukugwema lesi simo, kunemisebenzi noma izindlela zokuqinisekisa i-IP, okungukuthi, ukubheka ukuthi ngabe idatha efakwe ngumsebenzisi iyi-IP yini noma cha.

Lapha ngibashiya:

function validar_ip()
{
local  ip=$ipdudosa
local  stat=1
if [[ $ip =~ ^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]];
then
OIFS=$IFS
IFS='.'
ip=($ip)
IFS=$OIFS
[[ ${ip[0]} -le 255 && ${ip[1]} -le 255  && ${ip[2]} -le 255 && ${ip[3]} -le 255 ]] stat=$?
fi
return $stat
}

Lapho umsebenzisi engena "kokuthile", leyo nto kuzoba yinani lokuguquguqukayo kokungabaza ... ikhodi kuzoba:
echo "   Inserte lo que desea comprobar si es una IP."
read "ipdudosa"

Futhi manje sizokhombisa ukuqinisekisa okuqukethwe noma inani le- kokungabaza ngomsebenzi ongenhla, futhi lokhu kuzobheka ukuthi ngabe kuyi-IP yini noma cha. Uma kuyi-IP izosho kanjalo, uma kungenjalo izositshela ukuthi akuyona i-IP:

if validar_ip ipdudosa;
then echo "Sí, es una IP correcta :D";
else
echo "No, eso NO es una IP";
fi

Ngishiya umbhalo ophelele lapha:

Umsebenzi wokuqinisekisa i-IP (isibonelo)

Bheka ngokucophelela ukuthi ekuqaleni ngiyamemezela ukuthi: #! / bin / bash ... uma bebeka #! / bin / sh Lokhu ngeke kusebenze, ngichithe izinsuku ezi-2 ngicishe ngigcwele ukulwa nokubhikisha ngoba lo msebenzi awungisebenzelanga, futhi bekufanele ngisebenze sh esikhundleni se-bash hahaha.

Akunalutho olunye ongangeza ngalo, kukhona imisebenzi yalokhu ku Python, I-Perl nezinye izilimi ... empeleni, lena engikukhombisa yona akuyona ukuphela kwendlela yokuqinisekisa ama-IPs bash, kodwa bekulunge kakhulu kimi, yingakho ngiyihlanganyela 🙂
