comment How to get multiple lines out of a file by a regex?
I'm no whiz with sed, but it has a modifier N which adds a newline to the pattern space and then appends the next line of input to the pattern space. I think this will also allow you to search for things across more than one line. It's documented in info sed.

comment Reading and searching long man pages
You can also open man pages in the browser of your choice and use all of its tools. See askubuntu.com/questions/339255/…

comment Reading and searching long man pages
Another, even simpler alternative is to do 'man bash > bashman.txt'. Then you can just open bashman.txt in (another) window in your text editor and use all of it's commands for finding what you want. You can even edit the file to add tags for the sections you refer to most often. Making bashman.txt read-only helps so you don't modify it by accident in your editor.

comment What is the name of the shell feature `>(tee copyError.txt >&2)`?
I do a lot of bash, so I did a man bash > bashman.txt and made it read only. Now, I can load bashman.txt into another window in my text editor (read only) and use all the editor's facilities for searching and copying and pasting.

comment Bash script to get ASCII values for alphabet
There's also an ascii package for debian-based distros, but (at least now) the question is tagged as bash, so these wouldn't help the OP. In fact, it's installed on my system and all I get from man ascii is its man page.

comment Why not use “which”? What to use then?
@Rob and Stephane. I stand corrected about csh still being in widespread use. Your summary helps a lot. From the rest of your answer, it appears that it's just plain complicated and a simple answer would not have sufficed.

comment Why not use “which”? What to use then?
I've seen Stephane provide a lot of great answers to other questions. Although this answer probably has the right information in it, I was tempted to down vote it because it totally confused me. e.g. Does anyone use csh any more? Why cover it?

comment What are the differences between most, more and less?
In the special case of the man command, you can set the PAGER environment variable to any one of these pagers or to anything else that works to use as the pager for man pages. Here's one I wrote that uses your favorite browser as a pager so you don't have to use a new set of key bindings. dl.dropbox.com/u/54584985/kman

Just for completeness, trap '' debug turns this thing off again (two single quotes).

comment When to use redirection to stderr in shell scripts
@glts programs are always getting modified and improved. While the scripts you mention don't output any data now, they might later or you might use them as a starting points for other scripts that do. If you follow the convention to start with, you'll get a lot less surprises later. OTOH, if you just want to save the output to a file, then you have to redirect stderr, so it's a tradeoff like everything else.

comment How to recover from a chmod -R 000 /bin?
Glad it's fixed. I'm missing something. If it's a vm, then it's just one big file to the host system, isn't it? How do you mount anything inside it to do the repairs? (I understand how to do this on a non-vm system.)

comment Is it common to split larger script into multiple scripts and source them in the main script?
I have run into the same problem. I have a moderately large bash project sourceforge.net/projects/duplexpr . Currently, each script is self contained, but I am thinking of moving all the common functions to a separate file(s) and including them where needed to eliminate having to update them in multiple places. In general, I think it would be better to just call each successive script rather than source it. It makes running the parts independently possible. Then, you have to pass variables as arguments or in parameter files (or you can just export them if you don't want standalone.)

comment How do you send command line apps directly to the background?
If your task requires your input "before disappearing" into the background, you can use tools like zenity or yad (if you like guis). They can still send and receive output from the background. I'm sure that playing with pipes and devices would also get you access to the console from background, but I'm not sure how to do it.
