[SOLVED] Use Variables as a function

dellafaille · 06-16-2012, 04:18 AM

hi everyone!
i'd like to use 2 or more variables to create a function.

for exammple

opt1= Find / -type f -name *txt
opt2= 2>/dev/null

$opt1 $opt2 = opt3

$opt3
(now if i do this i only get my opt1 variable and not opt2
is there a way to get them both?)

Hello dellafaille!

You should use double quoting or even single quoting to make your "functions" strings and then simple catenate them

Code:

#!/bin/bash
opt1="echo 123"
opt2=" > Testfile"

echo "--$opt1----$opt2--"

opt3="$opt1""$opt2"

echo "-$opt3-"
eval "$opt3"
