comment Why is emacs not preinstalled?
It should be easy enough to install it yourself.

comment Do I have multiple python on my computer? and how to uninstall one of them?
Why remove python3.3? It's a newer version of the language -- and it typically doesn't provide an executable named "python" (it's named "python3"). It shouldn't conflict with your Python 2 installation, and removing it means you can't run any scripts that depend on Python 3. (You can almost think of Python 2 and Python 3 as two different languages.)

comment How to output only file names (with spaces) in ls -Al?
If you have a directory name "personal domain", how is the substring "personal" useful? And if you want to filter out the additional information other than the name, why are you using the -l option?

comment Will a shell script execute in Solaris? if not, which is the fastest way to make it compatible
@jlliagre: /bin/sh does exist on Solaris. Why would using it be a problem? Is it an older version of the shell?

Every UNIX-like system has a shell at /bin/sh. If you avoid features specific either to bash or to ksh, there shouldn't be a problem.

comment Why is number of open files limited in Linux?
@Lothar: Interesting. I wonder why the limits would differ. Given the fileno and fdopen functions I'd expect them to be nearly interchangeable.

comment What is the command for listing all users who are members of the admin group?
visudo edits the sudoers file; use it only if you want to modify it (yes, that's what the OP indirectly asked about). If you just want to view it, cat /etc/sudoers or less /etc/sudoers is sufficient. (You'll need root privileges for any of these, so sudo cat /etc/sudoers, for example.)

comment id command doesn't show all user's groups
The /etc/group file is the default way group information is stored. Systems can supplement it with other sources such as YP/NIS and LDAP. The id and getent commands will query whatever source(s) the system uses. (Likewise for /etc/passwd and several other databases).

comment What does the period indicate when an environmental variable is set like “VARIABLE_NAME=.”
@godlygeek: The root directory does have a .. entry. Another way to look at it is that every directory has a .. entry pointing to its parent -- and the root directory / is its own parent.

comment How to tell “cat” command to not hang on when there is no path provided?
cat "" doesn't hang, but it does print an error message: cat: : No such file or directory (referring to the empty string). It's better to test whether $1 exists, probably by checking the value of $#.

comment Fedora 20. Authentication requires a different password from su
su requires the password for the target account, root by default. Have you tried using sudo, which requires your password?

comment bash equivalent of this use of tcsh “sched” command?
I think I have a better solution that doesn't require using crontab. I'll update this answer (and delete this comment) once I've verified that it actually works.

The line in your question already does exactly what you want to do.

comment Does `sl` ever show the current directory?
You could always create the intermediate directories -- but then it wouldn't be showing (just) the contents of the current directory.

comment wget - corrupted directories
The command name is wget, and Unix command names are case-sensitive. I've seen documentation refer to it as Wget, but I've never seen it referred to as wGet.

Is there some significance to the spelling wGet rather than wget?

comment Does cron know that the instance to be scheduled is already running?
@Ouki: You should post that as an answer.

comment How to recover from recursive 'chmod -x' on my home folder
At least you didn't chmod -x the directories!
