It can be seen from the literal that the paste command and the cut command have the opposite function. The cut command extracts fields from the file line, while the paste command merges the file line information into one line.
The paste command is used as follows:

paste -d -s -file1 file2

The-s option combines the file rows into one row.
For example, the following files are available:

# paste 1.filenameallenbobchrisdyao

# paste 1.file -s name    allen    bob    chris    dyao

This command combines each line of the file into one line separated by the tab key.

-D specifies the separator. For example:

# paste -s -d - 1.file name-allen-bob-chris-dyao

Paste can splice multiple files by column, as shown below:

# paste 1.file 2.file  3.filename    sex    ageallen    mail    25bob    female    27chris    male    56dyao    mail    14    female    19

You can also splice multiple files by column:

# paste 1.file 2.file  3.file -sname    allen    bob    chris    dyaosex    mail    female    male    mail    femaleage    25    27    56    14    19

Of course, you can also specify the separator Number:

# paste 1.file 2.file  3.file -s -d:name:allen:bob:chris:dyaosex:mail:female:male:mail:femaleage:25:27:56:14:19

Or

# paste 1.file 2.file  3.file -d:name:sex:ageallen:mail:25bob:female:27chris:male:56dyao:mail:14:female:19
