Use Variables as a function
 
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?)

This should do the trick
 
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"

Regards, Heraton
