I'm looking for information on the -X
option of curl
. However, the documentation is quite lengthy and I have to scroll down for quite a long time to get to this option. Instead, I'd like to do something like
man curl | grep -X
to get the line containing "-X". (I would also do this in conjunction with the option -A 10
to get the 10 lines after the match). However, if I try this I get
grep: option requires an argument -- 'X'
Usage: grep [OPTION]... PATTERN [FILE]...
Try 'grep --help' for more information.
Any ideas on how to use grep
together with man
, or more generally on how to search man pages for specific lines?
You have to tell grep that -X
is not an option, but the pattern to look for:
man curl | grep -- '-X'
--
indicates the end of options. Without it, grep thinks that -X
is an option.
Alternatively, you can use -e
to indicate that what follows is a pattern:
man curl | grep -e '-X'
If you want to see the complete man page but skip directly to the first occurrence of -X
, you can use a command line option to less
:
man curl | less +/-X
Typing N repeatedly then takes you to the following occurrences.
man
will implicitly open in less
if you have it installed. So maybe you could read man page for less
.
less
actually supports search on it's own. Just press /
and write what you wanna search and enter
. Use n
to skip to next occurrence and N
for previous.
On most Linux systems, the default pager used by man
is less
.
If that is the case, you can search in a man
page using the / (slash) key followed by a query (here -X
) and finally hit ENTER . It will highlight all cases of -X
. It is of course possible that the first "hit" is not the one you want. In that case you can hit N to go to the ext hit and so browse through the entire document.内线命中,并在整个文档中,以便浏览。 In case you have jumped too far, you can use Shift + N to jump back to the previous hit.
This is not really an answer to the question how to handle this with grep
, but it is simply a way to efficiently search in man
.
You can read the man
page of less
( man less
) for further tricks on how to effectively use less
to improve your experience with man
pages.
