리눅스 문자와숫자 조합의 파일이름 정렬( Sort alphanumeric filenames in Linux )

아래 처럼 문자와 숫자가 섞여 있는 파일에 대해서 정렬이 제대로 되지 않을 때

When sorting is not done properly for files with mixed letters and numbers as shown below

[codehexa@codehexa test]$ ls -l

total 0

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t1

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t10

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t2

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t3

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t4

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t5

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t6

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t7

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t8

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t9

다음 sort 명령의 옵션을 통해 해결이 가능하다.

This can be resolved through the options of the following sort command.

[codehexa@codehexa test]$ ls -l | sort -V

total 0

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t1

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t2

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t3

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t4

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t5

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t6

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t7

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t8

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t9

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t10

역방향은 정렬은 r옵션을 추가하면 된다.

For the reverse direction, add the r option to sort.

[codehexa@codehexa test]$ ls -l | sort -Vr

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t10

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t9

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t8

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t7

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t6

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t5

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t4

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t3

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t2

-rw-rw-r-- 1 codehexa codehexa 0 Jun 28 14:34 t1
