I have some shell command. I would like to write the output to the standard output and save it into variable as well. I'd like to solve it with one command. I have tried these things.
ls > $VAR # redirects the output to file which name is stored in $VAR ls | tee -a $VAR # writes to standard output as well as in file which name is stored in $VAR VAR=`ls` # output into $VAR, but it is not sent to standard output VAR=`ls`;echo $VAR # ok, it works but these are two commands Any idea?

To store the output of a command in a variable, you can use the shell command substitution feature in the forms below: variable_name=$(command) variable_name=$(command [option ...] arg1 arg2 ...) OR variable_name='command' variable_name='command [option ...] arg1 arg2 ...'
Redirecting output to Multiple files and screen: If you want to redirect the screen output to multiple files, the only thing you have to do is add the file names at the end of the tee command.
How about:
VAR=$(ls | tee /dev/tty) great answer from @Gary_Barker, but this isn't possible on all systems.
On our teamcity there isn't a char-console. And there is another little problem.
If I use
VAR=$(ls -1); echo $VAR
it isn't the same like ls -1
My solution works, if it doesn't matter, that the output comes from error pipe.
VAR=$(ls -1 | tee >&2)
