Paste (Unix program)

Paste (Unix program)

The paste utility is a program found on Unix-like and otherwise POSIX-compliant operating systems. It is used to concatenate the contents of files for each corresponding line.

Usage

The paste utility is invoked with the following syntax:

paste ["options"] ["file1" ..]

Description

Once invoked, paste will read all its "file" arguments. For each corresponding line, paste will append the contents of each file at that line to its output along with a tab. When it has completed its operation for the last file, paste will output a newline character and move on to the next line.

Options

The paste utility accepts the following options:

-d "delimators", which specifies a list of delimiters to be used instead of tabs for separating consecutive values on a single line. Each delimiter is used in turn; when the list has been exhausted, paste begins again at the first delimiter.

-s, which causes paste to append the data in serial rather than in parallel; that is, in a horizontal rather than vertical fashion.

Examples

For the following examples, assume that names.txt is a plain-text file that contains the following information:

Mark SmithBobby BrownSue MillerJenny Igotit

and that numbers.txt is another plain-text file that contains the following information:

555-1234555-9876555-6743867-5309

The following example shows the invocation of paste with names.txt and numbers.txt as well as the resulting output:

$ paste names.txt numbers.txtMark Smith 555-1234Bobby Brown 555-9876Sue Miller 555-6743Jenny Igotit 867-5309

When invoked with the -s option, the output of paste is adjusted such that the information is presented in a horizontal fashion:

$ paste -s names.txt numbers.txtMark Smith Bobby Brown Sue Miller Jenny Igotit555-1234 555-9876 555-6734 867-5309

Finally, the use of the -d option is illustrated in the following example:

$ paste -d ., names.txt numbers.txtMark Smith.555-1234Bobby Brown,555-9876Sue Miller.555-6743Jenny Igotit,867-5309
