Linux Command - stat

The Linux stat command will show stats and info for a file or filesystem.

Check a file with stat:

stat test.txt

Dereference a link with “-L” and show the info for the dest file:

stat link.txt
stat -L link.txt

Show filesystem info:

stat -f test.txt

Terse format:

stat -t test.txt

Specify format:

stat -c "name: %n inode: %i type: %F"  test.txt

Specify format with escape chars:

stat --printf "name: %n\n\tinode: %i\n\ttype: %F\n"  test.txt

Filename and filesystem blocksize ( for faster transfers ):

stat -f -c "%n - %s" test.txt

-L	dereference, follow links
-f	show file system status
-t	terse format
-c “xxxx”	specify format:
–printf “xxxx”	Specify format and use escape characters:
