ls -qahlSr # list all files in size order - largest last

I find it useful, when cleaning up deleting unwanted files to make more space, to list in size order so I can delete the largest first.

Note that using "q" shows files with non-printing characters in name.

In this sample output (above), I found two copies of the same iso file both of which are immediate "delete candidates" for me.

ls -qaltr # list directory in chronological order, most recent files at end of list

I find it very handy to be able to quickly see the most recently modified/created files in a directory.

Note that the "q" option will reveal any files with non-printable characters in their filename.

Order all files oldest to newest then get the last one touched

On the Mac, the 'ls' function can sort based on month/day/time, but seems to lack ability to filter on the Year field (#9 among the long listed fields). The sorted list continuously increases the 'START' year for the most recently accessed set of files. The final month printed will be the highest month that appeared in that START year. The command does its magic on the current directory, and suitably discards all entries that are themselves directories. If you expect files dating prior to 2002, change the START year accordingly.

How to find all open files by a process in Solaris 10

Executing pfiles will return a list of all descriptors utilized by the process

We are interested in the S_IFREG entries since they are pointing usually to files

In the line, there is the inode number of the file which we use in order to find the filename.

The only bad thing is that in order not to search from / you have to suspect where could possibly be the file.

Improvements more than welcome.

lsof was not available in my case

List directories recursively showing its sizes using only ls and grep

ls -lhR

Lists everithing using -l "long listing format" wich includes the space used by the folder. Displays it in -h "human readable form" (i.e. 2.2G, 32K), and -R recurses subfolders.

grep -e using a regex, show lines containing the word "total" or a ":" at the end of the line (those with the name of the folder) only.

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.
