paste command is a Linux utility that merges lines of multiple files into a single file. It is used to concatenate files horizontally, meaning it takes the first line from each file and combines them into a single line, and repeats this process for all the lines in the files.
The basic syntax of the
paste command is:
paste [OPTION]... [FILE]...
FILE argument specifies the name of the files to be merged. If no file is specified,
paste reads from standard input.
Here’s an example of how to use the
Suppose you have two files,
file2.txt with the following contents:
$ cat file1.txt apple orange banana $ cat file2.txt red orange yellow
To merge the two files, use the following command:
$ paste file1.txt file2.txt apple red orange orange banana yellow
paste separates the merged lines with a tab character. You can specify a different delimiter using the
-d option. For example, to use a comma as the delimiter, use the following command:
$ paste -d ',' file1.txt file2.txt apple,red orange,orange banana,yellow
Here are the available options for the
||Specifies the delimiter to use between merged lines.|
||Concatenates the files sequentially instead of in parallel.|
||Terminates merged lines with a null character instead of a newline character.|
||Displays the help message and exits.|
||Displays the version information and exits.|
- If you get an error message saying that the file does not exist, double-check the spelling and path of the file.
- If the output is not what you expected, make sure the files have the same number of lines. If they don’t,
pastewill stop merging lines once it reaches the end of the shortest file.
pastecommand is often used in conjunction with other commands, such as
awk, to manipulate and process data.
- The output of
pastecan be redirected to a file using the
