REQUEST: jq is great for json - but is there a "jq for xml"? Some webservices are still only available in xml (e.g. uv levels). I currently use XMLStarlet for xml in the terminal. There are extra annoyances in xml that you can't avoid (like namespaces), but it could be a lot closer to jq.

echo 'Currently there are ' $(ver=(/bin /sbin /usr/bin /usr/sbin) && ls ${ver[*]} | wc -l) 'commands installed and available in the system'
This prints the man page of 3 random commands. One by one. Is a way to discover a few new commands each day. To go to the next command and exit press q. I hope you enjoy it.
commandoftheday=(/bin /sbin /usr/bin /usr/sbin) && ls ${commandoftheday} |sort -R |head -3 |xargs man '{}'
First of all, you might want to check out the subreddit: /r/commandline https://www.reddit.com/r/commandline/ general commands - awk/grep/sed/wc - text file processing - convert (image magick) - image processing tool - cpulimit - limit the cpu usage of a process - fdupes - check for duplicate files and optionally remove them - pdftk - concatenate pdf files and more - https://www.pdflabs.com/tools/pdftk-the-pdf-toolki…
Pdftk is a must. I use pdflatex also a lot of course. And R and psql.

The benefit of tmuxp is pretty clear from its README[1]. It gives this example: session_name: 4-pane-split windows: - window_name: dev window layout: tiled shell_command_before: - cd ~/ # run as a first command in all panes panes: - shell_command: # pane no. 1 - cd /var/log # run multiple commands in this pane - ls -al | grep \.log - echo second pane # pane no. 2 - echo third pane # pane no. 3 - echo forth pane # pan…
I use a shell script for such config. eg tmux split-window -h ; tmux send-keys "ls -la" C-m; ...

Thanks for your inputs. A few comments: I first created that script called m years ago on some Unix boxes that I was using. Could have been HP-UX or other version. And I've used it over the years on many Unix and Linux versions that I worked on. It could be that in some cases, the script is needed due to a tty or TERM or other configuration issue. But I'm pretty sure that I've had the need for it (to remove those con…
Yeah I'm familiar with groff et al. I used to get this issue on old UNIX boxes but not seen it in any of the Linux distros I use daily (not Freebase). The other thing worth trying is seeing whether your locals are set correctly and/or set the GROFF_TYPESETTER environment variable. Though this might only by GNU specific. Or just redirect the output (as suggested by the other reply) which is how I used to get around th…
Thanks again.

Also see the man page for the col command, which is used in my m script: http://man7.org/linux/man-pages/man1/col.1.html
I don't make a habit of commenting on shell scripts what I haven't first read. But thank you all the same. I used to use 'col' alot to resolve the tabs Vs spaces problem with different actors imposing different preferences in their source code. It's a handy tool but often overlooked.
Sorry, I should have added "if you haven't already read it", in my earlier comment.

Interesting, I may not have noticed or known about the tabs option of col. Cool. Seems it is like the entab program in an edition of the K&R C book.

I didn't know about the ANSI behavior, interesting.
>FWIW, if you need a fool-proof way to convert a man page to plain old ASCII with no escapes at all, it's easiest just to redirect the output of "man" to a file:
> man ls > ls.txt
IIRC, even with that way, the control chars still appeared in the file (at least on some Unix version), which is why I wrote the script in the first place.

Right
>and if you "cat" the file your terminal would probably ignore them
I think the terminal does not ignore them. My guess is that it interprets the characters, but it has no noticeable visual effect on the screen. E.g. if the letter "c" in "cat" is output as "c^hc" (to make in bold in print), the terminal will just print "c", a backspace, then "c" again, which to the user will look the same as a single "c".
