I have the following entry in my .bashrc:

PATH=$PATH:/home/user/abc/bin;export PATH; # ADDED BY INSTALLER - DO NOT EDIT OR DELETE THIS COMMENT

I want to substitute /home/user/abc/bin for any path that I choose. How can I do this with sed?

I have the following:

sed 's,PATH=[^;]*,PATH=$PATH/home/user/app/2.1,' -i ~/.bashrc

But, this will substitute anything that begins with PATH, how can I specify to only select what begins with PATH but also includes the string ADDED BY INSTALLER - DO NOT EDIT OR DELETE THIS COMMENT

    You do so:

    NEWPATH="your_new_path" sed -i "/ADDED BY INSTALLER - DO NOT EDIT OR DELETE THIS COMMENT/ s:/home/user/abc/bin:$NEWPATH:" .bashrc
