Convert text file formats between Windows and Linux

Problem: text that can be normally wrapped in Linux will not be wrapped in windows.

 

When changing a line in windows, there are two characters: Carriage Return (/R) and line feed (/N ). But in Linux, there is only one line feed (/N)

You can use unix2dos and dos2unix commands to convert the format:

Parameters:

-K: The timestamp of the output file and input file remains unchanged.

-O default file mode. Convert the file and output it to file

-N new infile OUTFILE mode. Convert infile and output it to OUTFILE

Assume that you use VI to create a text file and enter 123456

[Root @ centos test] #Ls-l a.txt

-RW-r -- 1 Root 7 Jan 7 21:31 a.txt

[Root @ centos test] #Hexdump-C a.txt

-RW-r -- 1 Root 7 Jan 7 21:31 a.txt

-RW ------- 1 Root 8 Jan 7 21:34 B .txt

[Root @ centos test] #Hexdump-C a.txt

B .txt is a converted DOS file.

 

2.Dos2unix

[Root @ centos test] #Dos2unix-N B .txt c.txt

Dos2unix: Converting file B .txt to file c.txt in UNIX format...

[Root @ centos test] #Ls-l

-RW-r -- 1 Root 7 Jan 7 21:31 a.txt

-RW ------- 1 Root 8 Jan 7 21:34 B .txt

-RW ------- 1 Root 7 Jan 7 21:38 c.txt

[Root @ centos test] #Hexdump-C B .txt
