Get a list of commands for which there are no manpages

This takes quite a while on my system. You may want to test it out with /bin first, or background it and keep working. If you want to get rid of the "No manual entry for [whatever]" and just have the [whatever], use the following sed command after this one finishes. sed -n 's/^No manual entry for \(.*\)/\1/p' nomanlist.txt
Sample Output
...
No manual entry for kwsdl_compiler
No manual entry for kxforms
No manual entry for kxkb
No manual entry for kxml_compiler
No manual entry for kxsconfig
No manual entry for kxsrun
No manual entry for lav2avi.sh
No manual entry for lavaddwav
No manual entry for lavinfo
No manual entry for lavtc.sh
...

  • use manpages, they give you "ultimate commands" "ls -SshF --color" list by filesize (biggest at the top) "ls -SshFr --color" list by filesize in reverse order (biggest at the bottom) Show Sample Output

  • Depending on the installation only certain of these man pages are installed. 12 is left out on purpose because ISO/IEC 8859-12 does not exist. To also access those manpages that are not installed use opera (or any other browser that supports all the character sets involved) to display online versions of the manpages hosted at kernel.org: for i in $(seq 1 11) 13 14 15 16; do opera http://www.kernel.org/doc/man-pages/online/pages/man7/iso_8859-$i.7.html; done

  • Obviously, you can replace 'man' command with any command in this command line to do useful things. I just want to mention that there is a way to list all the commands which you can execute directly without giving fullpath. Normally all important commands will be placed in your PATH directories. This commandline uses that variable to get commands. Works in Ubuntu, will work in all 'manpage' configured *nix systems. Show Sample Output


    3
    find `echo "${PATH}" | tr ':' ' '` -type f | while read COMMAND; do man -f "${COMMAND##*/}"; done

  • Search manpages for a keyword. Very useful when you don't know where to find the information. Show Sample Output

    man -k <keyword>

What Others Think

No need for sed or even the text file. for file in $(ls /usr/bin); do man -w $file 2>&1 | awk '/No/{print $5}'; done

This is a misuse of ls! for file in /usr/bin/*; do ; done is sufficient.
ScriptDevil · 408 weeks ago
@kaedenn Looks good. You should submit it as an alternate command. The reason for the extra file was so that I wasn't invoking sed several thousand times during the loop @ScriptDevil Have you even tried your way first? If I remove the ls command, I simply get a directory listing on stdout, not what I'm looking for. If it works for you , great, but either post a full, working command so we see what you tried, or don't post one because it appears to me that you didn't even test your method before posting. This is what I tried based on your post. I get stdout.txt full of the complete list of files, and stderr.txt is empty. for file in /usr/bin/*; do man -w $file 2>>stderr.txt 1>>stdout.txt; done

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
