命令简介：
dos2unix是将Windows格式文件转换为Unix、Linux格式的实用命令。Windows格式文件的换行符为\r\n ,而Unix&Linux文件的换行符为\n. dos2unix命令其实就是将文件中的\r\n 转换为\n。
而unix2dos则是和dos2unix互为孪生的一个命令，它是将Linux&Unix格式文件转换为Windows格式文件的命令。
命令语法：
dos2unix [options] [-c convmode] [-o file ...] [-n infile outfile ...]
unix2dos [options] [-c convmode] [-o file ...] [-n infile outfile ...]
命令参数：
此命令参数是Red Hat Enterprise Linux Server release 5.7下dos2unix命令参数，不同版本Linux的dos2nnix命令参数有可能不同。
参数
长参数
描叙
-h
显示命令dos2unix联机帮助信息。
-k
保持文件时间戳不变
-q
静默模式，不输出转换结果信息等
-V
显示命令版本信息
-c
转换模式
-o
在源文件转换，默认参数
-n
保留原本的旧档，将转换后的内容输出到新档案.默认都会直接在原来的文件上修改，

dos2unix Copyright (c) 1994-1995 Benjamin Lin
Copyright (c) 1998 Bernd Johannes Wuebben (Version 3.0)
Copyright (c) 1998 Christian Wurll (Version 3.1)
Usage: dos2unix [-hkqV] [-c convmode] [-o file ...] [-n infile outfile ...]
-h --help give this help
-k --keepdate keep output file date
-q --quiet quiet mode, suppress all warnings
always on in stdin->stdout mode
-V --version display version number
-c --convmode conversion mode
convmode ASCII, 7bit, ISO, Mac, default to ASCII
-l --newline add additional newline in all but Mac convmode
-o --oldfile write to old file
file ... files to convert in old file mode
-n --newfile write to new file
infile original file in new file mode
outfile output file in new file mode
2: dos2unix filename 将Windows格式文本转换为Unix&Linux格式文件
1: [root@DB-Server myscript]# cat -v test.sh
2: . /home/oracle/.bash_profile^M
3: echo ' '^M
4: date^M
5: echo ' '^M
6: ^M
7: sqlplus test/test @/home/oracle/scripts/test.sql^M
8: ^M
9: echo ' '^M
10: date^M
11: echo ' '^M
12: [root@DB-Server myscript]# dos2unix test.sh
13: dos2unix: converting file test.sh to UNIX format ...
14: [root@DB-Server myscript]# cat -v test.sh
15: . /home/oracle/.bash_profile
16: echo ' '
17: date
18: echo ' '
19:
20: sqlplus test/test @/home/oracle/scripts/test.sql
21:
22: echo ' '
23: date
24: echo ' '
3： dos2unix 可以一次转换多个文件
1: dos2unix filename1 filename2 filename3
4: 默认情况下会在源文件上进行转换，如果需要保留源文件，那么可以使用参数-n dos2unix -n oldfilename newfilename
1: [root@DB-Server myscript]# dos2unix -n dosfile linuxfile
2: dos2unix: converting file dosfile to file linuxfile in UNIX format ...
3: [root@DB-Server myscript]# cat -v dosfile
4: it is a windows dos file^M
5: you should convert to unix&linux format^M
6: [root@DB-Server myscript]# cat -v linuxfile
7: it is a windows dos file
8: you should convert to unix&linux format
9: [root@DB-Server myscript]#
clip_image001
5:保持文件时间戳不变
1: [root@DB-Server myscript]# ls -lrt dosfile
2: -rw-r--r-- 1 root root 67 Dec 26 11:46 dosfile
3: [root@DB-Server myscript]# dos2unix dosfile
4: dos2unix: converting file dosfile to UNIX format ...
5: [root@DB-Server myscript]# ls -lrt dosfile
6: -rw-r--r-- 1 root root 65 Dec 26 11:58 dosfile
7: [root@DB-Server myscript]# dos2unix -k dosfile
8: dos2unix: converting file dosfile to UNIX format ...
9: [root@DB-Server myscript]# ls -lrt dosfile
10: -rw-r--r-- 1 root root 65 Dec 26 11:58 dosfile
6：静默模式格式化文件
1: [root@DB-Server myscript]# unix2dos -q dosfile
2:
3: [root@DB-Server myscript]#
