Dotaz: bash - for a promenne

[petrT]

Ahoj, potreboval bych poradit se syntaxi. Chci udelat for, ktery bude postupne spoustet prikazy. Tedy neco takoveho:

COM="date pwd df"

for command in $COM;do $command;done

Nevim ale, jak to udelat abych mohl do COM zadavat i prikazy s parametry - napr. df -h. Muzete mi, prosim, poradit?

Diky!

Nehledas 'case'? Chces poustet prikazy dokola ?

[petrT]

Ne-e, case nehledam. Chtel bych spustit postupne nekolik prikazu.

COM="date pwd \"df -h\""

[petrT]

Tohle mi bohuzel nefunguje. Misto df -h dostanu na vystup

If '"df' is not a typo you can use command-not-found to lookup the package that contains it, like this: cnf "df

If '-h"' is not a typo you can use command-not-found to lookup the package that contains it, like this: cnf -h"

Pouzivam opensuse a bash.

a=('date -R' pwd 'df -h')
for x in "${a[@]}"; do $x; done

Vyuzit polia, ktore v bash-i su:

#!  /bin/bash

array=( 'date' 'ls -l' 'df -h' )

for cmd in "${array[@]}"
do
        $cmd
done

Možná by bylo lepší si nadefinovat funkci...

[Patrik Uhrak]

Toto riesenie sa mi paci este viac ako s poliami a prenositelnost (aj ked bolo ziadane v bashi) bude zrejme lepsia.

RunCmd(){
for cmd in "$@"
do
        $cmd
        shift
done
}
