Sort based on certain value in a column

Hi,

ST_F72_9S
SW_MH3_S6
Col_2
SW_MH3_AS7
ST_S15_9CH
SW_MH3_AS8
SW_MH3_ST
Col_3
ST_M93_SZ
ST_C16_TC


the output that i want is to sort based on "Col_X" (X is the number) as bold.

output.txt
Code:
Col_1
ST_F72_9S
SW_MH2_ST
SW_MH3_S6
Col_2
ST_S15_9CH
SW_MH3_AS7

WRAP-AND-SORT(1)					      General Commands Manual						  WRAP-AND-SORT(1)

NAME
wrap-and-sort - wrap long lines and sort items in Debian packaging files SYNOPSIS
wrap-and-sort [options] DESCRIPTION
wrap-and-sort wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that wrap-and-sort removes trailing spaces in these files. This script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and *.install in the debian directory. OPTIONS
-h, --help Show this help message and exit. -a, --wrap-always Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line. -s, --short-indent Only indent wrapped lines by one space (default is in-line with the field name). -b, --sort-binary-packages Sort binary package paragraphs by name. -k, --keep-first When sorting binary package paragraphs, leave the first one at the top. Unqualified debhelper(7) configuration files are applied to the first package. -n, --no-cleanup Do not remove trailing whitespaces. -d path, --debian-directory=path Location of the debian directory (default: ./debian). -f file, --file=file Wrap and sort only the specified file. You can specify this parameter multiple times. All supported files will be processed if no files are specified. -v, --verbose Print all files that are touched. AUTHORS
wrap-and-sort and this manpage have been written by Benjamin Drung <bdrung@debian.org>. Both are released under the ISC license. DEBIAN
