Apr 25	comment	can something besides the shebang set the interpreter? What's the value of `ls -ld /bin/bash` ?
Apr 17	comment	Check if folder is a mounted remote filesystem @TNW or even `/proc/mounts`
Mar 30	comment	Rsync — Itemized List of Changes Have you tried speeding up the rsync by using the `-W` flag? From `man rsync`: `-W, --whole-file copy files whole (w/o delta-xfer algorithm)`
Mar 30	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).
Mar 2	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.
Feb 21	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.
Feb 21	comment	find flags: -exec rm -rf vs -delete Even simpler: `rm -rf practice{1..10}`
Jan 30	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.
Jan 11	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.
Jan 11	comment	ddrescue: reread only good sectors? Using `dd` without a block size (`bs`) set makes FSM sad.
Jan 10	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.
Jan 9	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`.
Dec 28	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`.
Dec 24	comment	mkdir multiple directories with a subdirectory name having space in it This would also work: `mkdir -p project/level{' 1', 2}`
Dec 12	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.
Dec 9	comment	Automated SFTP upload with curl OP, please accept my answer if you found it acceptable.
Dec 9	comment	Copy files with deleting suffix in name This doesn't work with files with spaces
Dec 9	comment	Is there any way of prompt a message when a command in /usr/sbin/ is tried to run as nonroot? Did you source your .bashrc or close and open a new terminal?
Dec 4	comment	Rename multiple directories decrementing sequence number? while technically true, quoting is generally considered best practice.
Nov 29	comment	What distribution for light weight server? ArchLinux stands by it's slogan, but if you want a lightweight distro that doesn't take much effort/time to get up and running, then Ubuntu minimal is the way to go. I recently used in a project and got up and running in no time.
