Arch Linux sort installed packages by size

This, like the other commands listed here, displays installed arch packages. Unlike the other ones this also displays the short description so you can see what that package does without having to go to google. It also shows the largest packages on top. You can optionally pipe this through head to display an arbitrary number of the largest packages installed (e.g. ... | head -30 # for the largest 30 packages installed) Show Sample Output

Ping scanning without nmap

Usefull for when you don't have nmap and need to find a missing host. Pings all addresses from 10.1.1.1 to 10.1.1.254, modify for your subnet. Timeout set to 1 sec for speed, if running over a slow connection you should raise that to avoid missing replies. This will clean up the junk, leaving just the IP address: for i in {1..254}; do ping -c 1 -W 1 10.1.1.$i | grep 'from' | cut -d' ' -f 4 | tr -d ':'; done

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Check (partial) runtime-dependencies of Gentoo ebuilds

The output is only partial because runtime dependencies should count in also commands executed via system() and libraries loaded with dlopen(), but at least it gives an idea of what a package directly links to. Note: this is meaningful *only* if you're using -Wl,--as-needed in your LDFLAGS, otherwise it'll bring you a bunch of false positives.

Find all files under a certain directory /home that have a certain suffix at the end of the file name. Show the file and rename them to remove the suffix.

List all installed kernels on Ubuntu except current one

Lists all installed kernels minus the current one. This is useful to uninstall older kernels that take too much space on /boot partition.

Download YouTube Videos using wget and youtube-dl and just using the video link

in place of "output-filename.mp4" put the name you want the file to be named with. in place of "youtube-video-link" put the link of the Video page eg: http://www.youtube.com/watch?v=AclA-7YntvE in place of "format-number" put the number of the file format you would like How to get the "format-number" to get format number type in below command before running this command $ youtube-dl -F "youtube-video-link" and it will list all the available formats with the format number, like to download in 360p mp4 use the number "18" To automatically let it fetch the best quality available just remove the -f "format-number" and you are good to go.

Change/Modify timestamp

Shows size of dirs and files, hidden or not, sorted.

Very useful when you need disk space. It calculates the disk usage of all files and dirs (descending them) located at the current directory (including hidden ones). Then sort puts them in order.

Analyse an Apache access log for the most common IP addresses

This uses awk to grab the IP address from each request and then sorts and summarises the top 10.
