How to store command results in a shell variable? [duplicate]
I want to find out the number of directories and files in home directory and store that in a shell variable. I am using the following set of commands.
command="ls -l | grep -c \"rahul.*patle\""
eval $command
I want to store the result in a variable. How can I do this?
The syntax to store the command output into a variable is var=$(command).
So you can directly do:
result=$(ls -l | grep -c "rahul.*patle")
And the variable $result will contain the number of matches.
