Gudun Dokoki da yawa a cikin Linux ta amfani da Loop na ɗan lokaci

Dangane da hanyar da ta gabata, ana kuma iya amfani da madauki na ɗan lokaci don gudanar da umarni sau da yawa a cikin Linux ta amfani da haɗin gwiwar mai zuwa:

$ i=1; while [ $i -le n ]; do yourCommand_here; i=$(($i++)); done
OR
$ i=1; while [ $i -le n ]; do yourCommand_here; ((i++)); done

A cikin tsarin da ke sama, ina wakiltar madaidaicin ƙididdiga, [$i-le n] shine yanayin gwaji kuma n shine adadin lokutan da kuke son aiwatar da umarnin (mahimmanci adadin lokutan harsashi zai sake maimaita madauki.
