Console basedEdit

file (Unix)Edit

file (Unix) is a amazing little program that will give basic info on just about every file type. It does this by reading certain parts of the file to get basic stuff.

Usage

• Ececute: file FILE_TO_GET_INFO
  • Example: file movie.avi

Video

• Output: movie.avi: RIFF (little-endian) data, AVI, 624 x 352, 23.98 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)

Audio

• Output: audio.mp3: MPEG ADTS, layer III, v1, 320 kBits, 44.1 kHz, Stereo

Picture

• Output: photo.jpg: JPEG image data, JFIF standard 1.01

Text

• Normal text file
  • Output: textfile.txt: ASCII text
• PDF file
  • Output: document.pdf: PDF document, version 1.5
• Microsoft Word document
  • Output: document.doc: Microsoft Installer

ImageMagickEdit

• identify chop.jpg
  • Output: chop.jpg JPEG 343x350 343x350+0+0 8-bit DirectClass 88.5KB 0.010u 0:00.020

• identify -verbose chop.jpg
  • Output
