答案:sort -n -k2 file.txt 或则sort -g -k2 file.txt(从小到大排序)
-n, --numeric-sort
-g, --general-numeric-sort
sort -rn -k2 all_contig.txt (加-r从大到小排序)
使用方法:sort [选项]... [文件]...
Write sorted concatenation of all FILE(s) to standard output.


-b, --ignore-leading-blanks ignore leading blanks
-d, --dictionary-order consider only blanks and alphanumeric characters
-f, --ignore-case fold lower case to upper case characters
-g, --general-numeric-sort compare according to general numerical value
-i, --ignore-nonprinting consider only printable characters
-M, --month-sort compare (unknown) < JAN' < ... < DEC'
-n, --numeric-sort compare according to string numerical value
-r, --reverse reverse the result of comparisons

Other options:

-c, --check check whether input is sorted; do not sort
-k, --key=POS1[,POS2] start a key at POS1, end it at POS2 (origin 1)
-m, --merge merge already sorted files; do not sort
-o, --output=FILE write result to FILE instead of standard output
-s, --stable stabilize sort by disabling last-resort comparison
-S, --buffer-size=SIZE use SIZE for main memory buffer
-t, --field-separator=SEP use SEP instead of non-blank to blank transition
-T, --temporary-directory=DIR use DIR for temporaries, not $TMPDIR or /tmp;
multiple options specify multiple directories
-u, --unique with -c, check for strict ordering;
without -c, output only the first of an equal run
-z, --zero-terminated end lines with 0 byte, not newline

--version 输出版本号信息并退出

POS is F.C, where F is the field number and C the character position
in the field. OPTS is one or more single-letter ordering options, which
override global ordering options for that key. If no key is given, use the
entire line as the key.

SIZE may be followed by the following multiplicative suffixes:
% 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.

With no FILE, or when FILE is -, read standard input.

The locale specified by the environment affects sort order.
Set LC_ALL=C to get the traditional sort order that uses
native byte values.
