CentOS: bash: grep: command not found

Question

I have CentOS release 6.3

I'm trying to use grep in a script and I get bash: grep: command not found .

Any ideas how to fix this?

A few months ago it was working properly.

1. Locate your grep installation path. Most likely it's either /bin/grep or /usr/bin/grep .
2. echo "export PATH=$PATH:/<path_to_grep>" >> ~/.bash_profile . Note that ~/.bash_profile here means your bash startup file. The one that gets sourced on bash shell startup.

In case if you do not have grep for whatever reason or you just can't find / -iname "*grep*" - you can download and install it: gnu FTP . Any other reliable source is fine too. Then use steps 1 and 2 to add your grep directory to system path variable.
