|
- Sort a file in ascending order:
|
|
|
|
`sort {{path/to/file}}`
|
|
|
|
- Sort a file in descending order:
|
|
|
|
`sort {{[-r|--reverse]}} {{path/to/file}}`
|
|
|
|
- Sort a file in case-insensitive way:
|
|
|
|
`sort {{[-f|--ignore-case]}} {{path/to/file}}`
|
|
|
|
- Sort a file using numeric rather than alphabetic order:
|
|
|
|
`sort {{[-n|--numeric-sort]}} {{path/to/file}}`
|
|
|
|
- Sort `/etc/passwd` by the 3rd field of each line numerically, using ":" as a field separator:
|
|
|
|
`sort {{[-t|--field-separator]}} {{:}} {{[-k|--key]}} {{3n}} {{/etc/passwd}}`
|
|
|
|
- As above, but when items in the 3rd field are equal, sort by the 4th field by numbers with exponents:
|
|
|
|
`sort {{[-t|--field-separator]}} {{:}} {{[-k|--key]}} {{3,3n}} {{[-k|--key]}} {{4,4g}} {{/etc/passwd}}`
|
|
|
|
- Sort a file preserving only unique lines:
|
|
|
|
`sort {{[-u|--unique]}} {{path/to/file}}`
|
|
|
|
- Sort a file, printing the output to the specified output file (can be used to sort a file in-place):
|
|
|
|
`sort {{[-o|--output]}} {{path/to/file}} {{path/to/file}}`
