When I ssh to my Linux servers and use grep like this:
grep ‘timeout exceeded’ logfile | less
word wrap does not work.
However, if I use the same command but use less first, like this:
less logfile | grep ‘timeout exceeded’
the lines wrap. I am not sure what the problem is or if this is normal or not. But it happens regardless of the ssh client I use. I have tried both putty and an Ubuntu client. How can I fix this?
This is not the default behavior of
less. The default is to wrap long lines.
You are seeing this behavior because you have the
-S option (and several others) set in your
LESS environment variable.
-S or --chop-long-lines Causes lines longer than the screen width to be chopped (trun‐ cated) rather than wrapped. That is, the portion of a long line that does not fit in the screen width is not shown. The default is to wrap long lines; that is, display the remainder on the next line.
To resolve the problem, check your shell startup scripts (e.g.
$HOME/.bashrc) and the system shell startup scripts (e.g. those in the
/etc/profile.d directory) to see where the environment variable is being set, and make the desired changes.
