We’re often not that eager to know the tools we got used to. less
is a good example for that. Did you know(?) it can:
- show/unshow line numbers:
-N
- select position you want to see using percentage – say, let’s jump to ⅓ (33 %) of the log:
33p
- chop long line (say “goodbye!” to MySQL’s
\G
when output is wide and you usedpager less
):-S
- squeeze multiple blank lines so you have less pages to deal with:
-s
- Display only (non-)matching lines (say “bye-bye!” to
fgrep foo bar | less
):&
- pipe the whole file or a part of it through filter you’ve chosen:
|
- run editor for the file in question:
v
Do yourself a favor and just press h
when in less
– I bet you won’t regret that now you’d know less. ;-)
