# To disable the terminal refresh when exiting
less -X

# To save the contents to a file
# Method 1 - Only works when the input is a pipe
s <filename>

# Method 2 - This should work whether input is a pipe or an ordinary file.
Type g or < (g or less-than) | $ (pipe then dollar) then cat > <filename> and Enter.

less +F filename.log
# Using +F option or pressing F in less is similar to `tail -f filename.log` but can use less his features.

less -j2 /var/log/syslog
# Set the search jump target to 2 lines down so that you see the previous line of context on searches within less. 
# FYI, in less if you set -j-1 (value -1), it will put the match at the bottom of the terminal. -j-2 = two lines up. -j.5 = at half screen.

less tip: press 10<rightarrow> 
# to move 10 spaces to the right and left to move left, etc. You can use numeric prefixes for many commands.

less -j10 /var/log/syslog 
# Set the search jump target to 10 lines down so that you see 9 previous lines of context on searches within less.

less log log.2 log.3 | grep " 404 " | more 
# Did you know that if your output from 'less' is a pipe, it behaves like cat. Undocumented

# "Where is that damn rehearsal email at?" Check files modified in the past 30 days with the word rehearsal in them. Within less, use :n to view to the next file.
less $( grep -li rehearsal $( find Maildir -type f -mtime -30 ) )
