How to determine the type of a file in Linux
Answer:
The file command is what you need, e.g.
# file /bin/gzip
/bin/gzip: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.15
# file /usr/share/doc/apt/changelog.gz
/usr/share/doc/apt/changelog.gz: gzip compressed data, from Unix,
max compression
