what does a backslash followed by grep mean?
bash, grep
Solution
`\grep` means execute `system default grep` from `/bin/grep` OR `/usr/bin/grep` ignoring all local environment aliases you may have set up for `grep`.
- You can put backslash before any BASH command to ignore aliases with the same name.
Example:
> alias grep=date
> grep
Thu Nov 28 22:49:57 EST 2013
> \grep
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
Problem
I am following an impatient way of learning and working with bash scripts, in this link I saw a line like this: ``` INSTALLED=$(dpkg -l \grep $1) ``` can you tell me what \grep means? thanks
