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 kxforms
No manual entry for kxkb
No manual entry for kxml_compiler
No manual entry for kxsconfig
No manual entry for kxsrun
No manual entry for lav2avi.sh
No manual entry for lavaddwav
No manual entry for lavinfo
No manual entry for lavtc.sh
...
```

for file in $(ls /usr/bin ) ; do man -w $file 2>> nomanlist.txt >/dev/null ; done

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"
