Get a list of commands for which there are no manpages

This takes quite a while on my system. You may want to test it out with /bin first, or background it and keep working. If you want to get rid of the "No manual entry for [whatever]" and just have the [whatever], use the following sed command after this one finishes. sed -n 's/^No manual entry for $.*$/\1/p' nomanlist.txt Show Sample Output
This is sample output - yours may be different.
```
...
No manual entry for kwsdl_compiler

No manual entry for kxsconfig
No manual entry for kxsrun
No manual entry for lav2avi.sh
No manual entry for lavaddwav

```

Display a random man page

Broaden your knowledge of the utilities available to you in no particular order whatsoever! Then use that knowledge to create more nifty one-liners that you can post here. =p Takes a random number modulo the number of files in $dir, prints the filename corresponding to that number, and passes it as an argument to man.

-2

dir="/bin"; man $(ls $dir |sed -n "$(echo $(( $RANDOM % $(ls $dir |wc -l | awk "{ print $1; }" ) + 1 )) )p")

Display a random man page

Great idea camocrazed. Another twist would be to display a different man page based on the day of the year. The following will continuously cycle through all man pages: man $(ls /bin | sed -n $(($(date +%j) % $(ls /bin | wc -l)))p)
This is sample output - yours may be different.
-2

man $(ls /bin | sed -n $((RANDOM % $(ls /bin | wc -l) + 1))p)

putnamhill · 2010-08-20 17:15:33 5
Display a random man page

Another one. Maybe not the quicker because of the sort command, but it will also look in other man sections. updated with goodevilgenius 'shuf' idea

Rename files in a directory in an edited list fashion

Instead of tedious manual mv commands and tabbing, this routine creates a file listing all the filenames in the PWD twice, edit the second instance on each line to the new name, then save the file, the routine does the rest. Feel free to replace nano with your holy war editor of choice. You will get a lot of "mv: 'x' and 'x' are the same file" warnings, these could be cleaned up but the routine works.

Get the /dev/disk/by-id fragment for a physical drive

This was tested on Ubuntu 12.04 (Precise) LTS Server. It returns the name of the symlink within /dev/disk/by-id for the physical drive you specify. Change /dev/sda to the one you want, and replace ata- with scsi- or the appropriate type for your drive. I used this to pre-configure grub-pc during a non-interactive install because I had to tell it which disk to install grub on, and physical disks don't have a UUID such as that blkid provides.
This is sample output - yours may be different.
-2

ls -l /dev/disk/by-id | egrep ata-.*`hdparm -i /dev/sda | grep SerialNo | sed 's/.*SerialNo=//' | tr -d "\n"`.*sda$ | sed -e 's/.*ata-/ata-/' -e 's|[ ].*||' | tr -d "\n"

check for write/read permissions

su www-apache/ftp user and then check readable: find ~/ -type d $ -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' $ -prune -o -exec test -r {} \; -exec echo {} readable \; 2>/dev/null check writable: find ~/ -type d $ -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' $ -prune -o -exec test -w {} \; -exec echo {} writable \; 2>/dev/null

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

move you up one directory quickly

Alias a single character 'b' to move to parent directory. Put it into your .bashrc or .profile file. Using "cd .." is one of the most repetitive sequence of characters you'll in the command line. Bring it down to two keys 'b' and 'enter'. It stands for "back" Also useful to have multiple: alias b='cd ../' alias bb='cd ../../' alias bbb='cd ../../../' alias bbbb='cd ../../../../'

Play all files in the directory using MPlayer

Skip forward and back using the < and > keys. Display the file title with I.

Does a traceroute. Lookup and display the network or AS names and AS numbers.

From the man page. lft ? display the route packets take to a network host/socket using one of several layer-4 protocols and methods; optionally show heuristic network information in transitu -A Enable lookup and display of of AS (autonomous system) numbers (e.g., [1]). This option queries one of several whois servers (see options 'C' and 'r') in order to ascertain the origin ASN of the IP address in question. By default, LFT uses the pWhoIs service whose ASN data tends to be more accurate and more timely than using the RADB as it is derived from the Internet's global routing table. -N Enable lookup and display of network or AS names (e.g., [GNTY-NETBLK-4]). This option queries Prefix WhoIs, RIPE NCC, or the RADB (as requested). In the case of Prefix WhoIs or RADB, the network name is displayed. In the case of RIPE NCC, the AS name is displayed.

delay execution of a command that needs lots of memory and CPU time until the resources are available

[ 2000 -ge "$(free -m | awk '/buffers.cache:/ {print $4}')" ] returns true if less than 2000 MB of RAM are available, so adjust this number to your needs. [ $(echo "$(uptime | awk '{print $10}' | sed -e 's/,$//' -e 's/,/./') >= $(grep -c ^processor /proc/cpuinfo)" | bc) -eq 1 ] returns true if the current machine load is at least equal to the number of CPUs. If either of the tests returns true we wait 10 seconds and check again. If both tests return false, i.e. 2GB are available and machine load falls below number of CPUs, we start our command and save it's output in a text file. The ( ( ... ) & ) construct lets the command run in background even if we log out. See http://www.commandlinefu.com/commands/view/3115/ .

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

For Gentoo users : helping with USE / emerge

This command puts all the flags of the USE variable actually used by the packages you emerged to the file "use", and those which are unused but available to the file "notuse"

Lists all usernames in alphabetical order

Save some CPU, and some PIDs. :)
