When you are shown that fgrep on some systems has a --color option (as in the fgrep man page excerpt vgersh99 provided), the way to get color output from fgrep would be:

Code:

fgrep --color -i "XYZ-1124354-P" mylog.log

but, you haven't told us what system you're using, so we don't know if fgrep on your system supports the --color option.

Furthermore, many utilities that have color options use the file descriptor associated with the utility's standard output to determine terminal characteristics to determine what escape sequences are needed to produce color on the terminal you're using. If your system's grep family of utilities supports a --color option and uses stdout to determine terminal type, piping the output from fgrep into another utility will disable color output. If your fgrep can't produce color output when stdout is connected to a pipe, you could still translate ASCII soh control characters to spaces using:

Code:

tr '\001' ' ' < mylog.log | fgrep --color -i 'XYZ-1124354-P'

but using sed G to produce double spaced output will be more complex:

Code:

fgrep -i 'XYZ-1124354-P' mylog.log | tr '\001' ' ' | sed G | grep --color -i -e 'XYZ-1124354-P' -e '^$'
