Linux paste command

Linux 命令大全Linux Command Collection

The Linux paste command is used to merge columns of files.

The paste command merges each file column by column.

Syntax

paste [-s][-d <间隔字符>][--help][--version][文件...]

Parameters：

  • -d<delimiter> or --delimiters=<delimiter> Use the specified delimiter character instead of the tab character.
  • -s or --serial Process serially rather than in parallel.
  • --help Online help.
  • --version Display help information.
  • [file...] Specify the file path(s) to operate on.

Examples

Use the paste command to merge the files "file", "testfile", and "testfile1". Enter the following command:

paste file testfile testfile1 #合并指定文件的内容

However, before executing the above command, first use the "cat" command to view the contents of the three files, as shown below:

$ cat file                  #file文件的内容  
xiongdan 200  
lihaihui 233  
lymlrl 231  
$ cat testfile              #testfile文件的内容  
liangyuanm  ss  
$ cat testfile1             #testfile1文件的内容  
huanggai 56  
zhixi 73

After executing the merge command "$ paste file testfile testfile1", the program interface will display the merged file contents as shown below:

xiongdan 200  
lihaihui 233  
lymlrl 231  
liangyuanm  ss  
huanggai 56  
zhixi 73

If you use the "-s" parameter of the paste command, you can merge multiple lines of data in a file into one line for display. For example, to merge the 3 lines of data in file "file" into one line for display, enter the following command:

$ paste -s file             #合并指定文件的多行数据

After the above command is executed, the displayed data content is as follows:

xiongdan 200 lihaihui 233 lymlrl 231

Note: The "-s" parameter only adjusts the display mode of the testfile file contents and does not change the format of the original file.
