- Give a description of the type of the specified file. Works fine for files with no file extension:
2015-12-29 03:47:17 +00:00
`file {{path/to/file}}`
2015-12-29 03:47:17 +00:00
- Look inside a zipped file and determine the file type(s) inside:
2015-12-29 03:47:17 +00:00
2015-12-29 05:33:04 +00:00
`file -z {{foo.zip}}`
2016-01-08 09:15:59 +00:00
2016-01-13 11:04:46 +00:00
- Allow file to work with special or device files:
2016-01-08 09:15:59 +00:00
`file -s {{path/to/file}}`
2016-01-08 09:15:59 +00:00
2016-01-13 11:04:46 +00:00
- Don't stop at first file type match; keep going until the end of the file:
2016-01-08 09:15:59 +00:00
`file -k {{path/to/file}}`
2017-02-16 19:09:06 +00:00
