How can I copy the records of the file Ã¢Â€Âœ/etc/bashrcÃ¢Â€Â that have the Ã¢Â€ÂœTMOUTÃ¢Â€Â string except those containing the Ã¢Â€Âœread-onlyÃ¢Â€Â string, to the file?

grep 'TMOUT' /etc/bashrc | grep -v 'read-only' >output

This first extracts all lines from /etc/bashrc that contains the string TMOUT. The second grep removes all of those lines that also contain the string read-only. The output is saved to the file output.

With just one command:

awk '/TMOUT/ && !/read-only/' < /etc/bashrc > output

Or:

sed '/TMOUT/!d; /read-only/d' < /etc/bashrc > output

(delete the lines that don't (!) contain TMOUT and those that contain read-only).

Those also have the advantage of not clobbering the output file if /etc/bashrc can't be opened.
