File (command)
From Linuxintro
(Redirected from File)
file is a command to find out the type of a given file. Because for Linux, "everything is a file", it can distinguish a lot:
- hard disks
# file /dev/sda1 /dev/sda1: block special (8/1)
- file systems
# file -s /dev/sdc /dev/sdc: Linux rev 1.0 ext3 filesystem data (needs journal recovery) (large files)
- directories
# file /tmp /tmp: sticky directory
- links
# file /lib64/libkeyutils.so.1 /lib64/libkeyutils.so.1: symbolic link to `libkeyutils-1.2.so'
- normal files
# file /lib64/libkeyutils-1.2.so /lib64/libkeyutils-1.2.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), stripped
