sort

Sort lines of text files.

• Sort a file in ascending order:

sort {path/to/file}

• Sort a file in descending order:

sort --reverse {path/to/file}

• Sort a file in case-insensitive way:

sort --ignore-case {path/to/file}

• Sort a file using numeric rather than alphabetic order:

sort --numeric-sort {path/to/file}

• Sort `/etc/passwd` by the 3rd field of each line numerically, using ":" as a field separator:

sort --field-separator={:} --key={3n} {/etc/passwd}

• Sort a file preserving only unique lines:

sort --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 --output={path/to/file} {path/to/file}

• Sort numbers with exponents:

sort --general-numeric-sort {path/to/file}
