comment scp and compress at the same time, no intermediate save
A good note to add is that unless you're transferring over a generally slow network, say the internet, it's best to avoid compressing as it just slows down the transfer rate. On a LAN, -z is at least twice as slow. For even more speed than rsyncing over ssh, setup an rsync daemon and rsync using -W flag (copies files whole (w/o delta-xfer algorithm).

comment faster alternative to cp -a
I wouldn't trust that article too much. I use rsync quite frequently and regular copy at 130-170 MB/sec.

comment Which distribution is usually chosen in an enterprise environment - Debian or RHEL (CentOS)?
Your question is open to debate and therefore not fit for this site. Flagged.

comment Why do I get fsync() failed: Disk quota exceeded on my linux machine?
Is quota configured? Run quotacheck -a and look at the output.

comment Count appearance of a variable in another file
That would skew the results. If you have more than one instance per line, suddenly your counted results aren't accurate.

comment ddrescue: reread only good sectors?
Using dd without a block size (bs) set makes FSM sad.

comment Count appearance of a variable in another file
No need to pipe to wc -l and count lines; grep can already count occurrences with the -c option.

comment Change default path for when I SSH in to CentOS server?
It's better to use usermod when changing anything concerning a user that writes to /etc/passwd, to prevent mistakes: usermod -d /home user.

comment 'kill java' doesn't kill java
kill -9 is generally a last resort. It's better to try kill -11 then kill -6 first. If kill -11 doesn't kill it, kill -6 usually does. Try kill -11 first, wait a few/several seconds, and if the process is still alive, try kill -6. Wait several seconds and if it still isn't dead, you can then try kill -9.

This would also work: mkdir -p project/level{' 1', 2}

comment /: is a directory issue in bash
Upvoted. The shell will interpreted text separated only by slashes as directories, not commands/arguments. The forward slash can be used in arguments of, for example, Perl scripts (requires configuring Getopt::Long or rolling your own), but still requires the space between the command and arguments -- again, this is a shell requirement.
