comment How can I end a here-document that starts with <<\\$fff?
Pedagogically, why would you put a question like that on a test? It's a corner case at best, probably a worst practice, and easily and habitually avoided by every "here document" writer ever. Sometimes you've gotta wonder about academics...

comment What does this grep expression mean?
We need to see the exact command you invoke. As it stands, the backslashes might be to protect '*' and '?' from shell expansion, or to keep grep from treating them as metacharacters.

comment I keep getting error: PHP Startup - libphp5.so missing? PHP seems to run fine with Apache
@PancakeMaker - last things I can think of is to look in /var/log/httpd/error_log when you run the PHP script from the web. You may also want to go into /etc/php/php.ini and turn up error reporting: "error_reporting = E_ALL" and "display_errors = On" and "display_startup_errors = On". That might give you some extra info to go on. Also: now that you're getting a different error, open a new question, complete with version numbers for all the packages involved, and the smallest piece of PHP that triggers the problem.

comment I keep getting error: PHP Startup - libphp5.so missing? PHP seems to run fine with Apache
@PancakeMaker - my mistake. It's the "apache" package. Try un-installing and re-installing "apache". pacman -Q apache tells me "apache 2.4.12-4"

comment delete lines of a file from a file
@aroraa - I don't think so. sed has a different idea of how lines are numbered, because it never "backs up", and it has a sequence of input lines. The sed -f solution is probably the best - less work than mine.

@PancakeMaker - do nm -D /usr/bin/httpd | grep ap_server_root to see if the Apache executable even has that symbol defined in it. Also, is package "httpd" up to date? pacman -S httpd should show you.

comment Output of wc | awk is different in shell script than from cli
There's something going on that you haven't written down. You have a string "somprocess". What's that string in the real script? What's your interactive shell? What version is /bin/bash and your interactive shell? For instance pgrep awk | wc | awk '{print $1}' says 0 for interactive zsh, but 1 for bash and dash.

comment Is it possible to make an exec call that “returns”?
Apparently it's possible to change a parent process's environment: stackoverflow.com/questions/205064/… But that seems terribly hacky.

comment I keep getting error: PHP Startup - libphp5.so missing? PHP seems to run fine with Apache
@PancakeMaker - ap_server_root is a .BSS segment symbol (C language global variable) in httpd: nm -D /usr/bin/httpd| grep ap_server_root Are you certain you have a good installation of Apache? Is the ServerRoot value set in /etc/httpd/conf/httpd.conf, and is it correct?

comment directory structure vs file system
@MaxNanasy - given that two meanings of "file system" are in common use (1. The names and arrangement of directories in a tree structure, and 2. The on-disk format and layout of file and directory structured data, along with the code to maintain and use it), it's pretty hard to come up with a term that's both comprehensible, not defined in a circular fashion, and technically correct. I chose to go with comprehensible and used "partition" instead of other terms. I invite you to suggest term(s) that are more correct, I'm at a loss.
