Hi, folks!
See the examples:
bash$ X="ls"; $X
file1 file2 file3
*** Works correctly!
bash$ X="ls | wc"; $X
ls: |: No such file or directory
ls: wc: No such file or directory
*** Doesn't work!
How to make the last command work correctly as first?
Thanks in advance!

Hi,
if you want to store command result in variable use back quote:
# X=`ls | wc`
# echo $X.
or use command alias:
# alias X="ls | wc"
# X
if you want to store command result in variable use back quote:
# X=`ls | wc`
# echo $X.
or use command alias:
# alias X="ls | wc"
# X

juppe10a,
It's not exactly what I was looking for, cause the command result isn't important to store to a variable, but the command execution itself.
I found a perfect way to do that:
# X="ls | wc"; eval $X
Simple but functional.
Thanks anyway!
