Paste:linux merge columns from two files (merge left and right)

[email protected] ~]# paste [-d] file1 file2

Options and Parameters:

-D: The delimiter character can be followed. The default is delimited by [tab]!

-: If the file section is written--indicates the meaning of the data from standard input.

Example one: Put/etc/passwd with/etc/shadow on the same line

[Email protected] ~]# Paste/etc/passwd/etc/shadow

Bin:x:1:1:bin:/bin:/sbin/nologin Bin:*:14126:0:99999:7:::

Daemon:x:2:2:daemon:/sbin:/sbin/nologin Daemon:*:14126:0:99999:7:::

Adm:x:3:4:adm:/var/adm:/sbin/nologin Adm:*:14126:0:99999:7:::

# Watch out! The middle of the same line is separated by the [tab] key!

Example two: first read the/etc/group (with cat) and then paste it together with the example! And only the first three rows are removed

[Email protected] ~]# Cat/etc/group|paste/etc/passwd/etc/shadow-|head-n 3

# The focus of this example is on that-the use! That stuff always stands for stdin Oh!

Example: Using CHPASSWD to bulk Modify user passwords
