-g | --general-numeric-sort

Comparison by general value

-i | --ignore-nonprinting

Only ASCII characters between 040 and 176 are considered

-M | --month-sort

Sort by month

-h | --human-numeric-sort

Sort by readable data, e.g. 1K, 2G

-n | --numeric-sort

Sort by numerical size

-R | --random-sort

Random hash sort of keys

--random-source=FILE

Get random bytes from a file

-r | --reverse

reverse arrangement

--sort=WORD

Sort by given requirements: general-numeric -g, human-numeric -h, month -M, numeric -n, random -R, version -V

-V | --version-sort

Sort by version number

--batch-size=NMERGE

Merge NMERGE inputs at most once; use temp files more often

-c | --check | --check=diagnose-first

Check if sorted, not sorted

-C | --check=quiet | --check=silent

As with "-c," don't report the first bad line

--compress-program=PROG

Time compression with prog, decompression with prog-d

--files0-from=F

Reads input from the file specified by the name ending in NUL in file F; if F is-, reads the name from standard input.

-k | --key=POS1[,POS2]

3. Examples

1) Direct sorting

[root@192 weijie]# cat 1.c

1K

1M

1G

1T

[root@192 weijie]# sort 1.c //Direct comparison character sort

1G

1K

1M

1T

2) Sort by readable units

[root@192 weijie]# sort -h 1.c //The contents of the file are sorted in units, which are obviously memory size units

1K

1M

1G

1T

3) Sort by number

[root@192 weijie]# cat 2.c

123

23

212

[root@192 weijie]# sort 2.c //Default sort, compare character by character

123

212

23

[root@192 weijie]# sort -n 2.c //Sort content as a number
