Write output or command to variable (shell)
 

Hi i want to write an output of a command to a variable, How do I do this is shell script ?

Many Thanks.

I presume you mean in a bash command...? Something like this...?

Note the quotes after the = sign are back ticks:
` not ' or "

Yup that worked thanks.

or use set:

If you were asking about doing it within a bash script, run info bash and look at the descriptions of the $(expression) and ${expression} constructions.

its ment to read output "of"

Cute.
You learn something all the time.

Hey, let's try this
who.out=`who | wc -l`
echo $who.out # who.out is your output variable
(or)
LS=`ls -l` # place the value of ls-l into variable LS
echo $LS # and LS is your output of variable

or lots of vars:


for var in $(ls /); do
echo $var
done



no fan mail please
:))

i can't help myself...

create a little script:

#!/bin/sh
lsmsg=hello
for var in $(ls /); do
echo $var-$lsmsg
done

make an alias:
alias ls=scriptname

now, type ls
nice?
alas the many ways to personalize your pc.

cheers

ps:
want to get rid of the new and improved ls command?
unalais ls
