I am not clear as to what exactly you want.

alias testin='ls -a'

testin would now give what 'ls -a' would give.

my script will do

testin=`ls -a`

echo $testin >> out.txt

and also i want to include that ls -a command to that file.

type testin >> some_file
Also, you do not need to do echo $testin >> some_file, you need to do as follows.

testin >> some_file

Hi Venkat:

Perhaps this is what you want (by example):

# CMD="ls -l /var/tmp";{ echo executing: $CMD;$CMD; } > file

Just to break it down to its most simple form, If I understand what you want

echo â output from ls â a commandâ > file.out
testin=$(ls â a)

echo $testin >> file.out

in this case $( ) works just like the back tick ` `

ok, lets try that again

echo "output from ls -a command" > file.out
testin=$(ls -a)

echo $testin >> file.out

see if that prints better

Venkat,

If you want to capture the output of the command as well as the executed command then "script" might be what you're looking for...man script(1)

cheers!

" want to output the 'ls -a' to some file and also will include what command i executed for this output eg:'la -a' "

CMD="ls -a"
echo "$CMD" > /tmp/file
$CMD >> /tmp/file

This answers your question but is not very elegant. Setting a variable to the output of a command as you posted originally is not a good idea. It would work provided you put double quotes aruond the grave accented command provided there are not too many files present.

Suggest you just do:

ls -a > /tmp/file

and be done with it.
