Create backup copy of file, adding suffix of the date of the file modification (NOT today's date)

When I go to change a configuration file I always like to make a backup first. You can use "cp -p" to preserve the modification time, but it gets confusing to have file.prev, file.prev2, etc. So I like to add a YYMMDD suffix that shows when the file was last changed. "stat -c %Y" gives you the modification time in epoch seconds, then "date -d @" converts that to whatever format you specify in your "+format" string. Show Sample Output

```
# ls -l
-rw-r--r-- 1 root root 0 Dec 31  2018 file
# cp -p file file.$(date -d @$(stat -c '%Y' file) "+%y%m%d")
 ls -l
-rw-r--r-- 1 root root 0 Dec 31  2018 file
-rw-r--r-- 1 root root 0 Dec 31  2018 file.181231

Trim disk image for best compression before distributing

fstrim is usually used on SSDs but can also be used to remove useless bits from file system images. This is most helpful if the compressed disk image is intended to be distributed, since it will be smaller than an untrimmed compressed image. Show Sample Output

Manually trim SSD

Trims left over file system data from SSD. This can be set as a mount option, but then IO performance decreases. I prefer to trim in a batch either on boot or every few weeks. Show Sample Output

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

leave a stale ssh session

When your ssh session hanged (probably due to some network issues) you can "kill" it by hitting those 3 keys instead of closing the entire terminal.

Show apps that use internet connection at the moment. (Multi-Language)

Create a DOS floppy image

mount with: mount -t msdos -o loop ./floppy.img /tmp/mnt

Securely destroy data (including whole hard disks)

GNU shred is provided by the coreutils package on most Linux distribution (meaning, you probably have it installed already), and is capable of wiping a device to DoD standards. You can give shred any file to destroy, be it your shell history or a block device file (/dev/hdX, for IDE hard drive X, for example). Shred will overwrite the target 25 times by default, but 3 is enough to prevent most recovery, and 7 passes is enough for the US Department of Defense. Use the -n flag to specify the number of passes, and man shred for even more secure erasing fun. Note that shredding your shell history may not be terribly effective on devices with journaling filesystems, RAID copies or snapshot copies, but if you're wiping a single disk, none of that is a concern. Also, it takes quite a while :)

share internet connection with only one network interface

the below command create a alias for share your internet connection with another. $ifconfig eth0:1 192.168.0.1/24 Its obviously necessary too activate the iptables post-routing and ip forwarding, as root: $modprobe iptable_nat $iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE $echo 1 > /proc/sys/net/ipv4/ip_forward Be sure that the alias 192.168.0.0/24 is not your active real ip range

print text in color red

eg: $printTextInColorRed foo bar foo bar [in red color]

Compress files found with find

tar options may change ;) c to compress into a tar file, z for gzip (j for bzip) man tar -print0 and -0t are usefull for names with spaces, \, etc.

Play musical notes from octave of middle C

Are there any creative pieces of music that can be created using beep and the shell? I'd love to hear it!

Convert mp3/wav file to asterisk ulaw for music on hold (moh)

Install pip with Proxy

Installs pip packages defining a proxy
