paste Linux command
The Linux paste command is used to merge lines of files to standard output. By default, it concatenates lines from each input file side-by-side, separated by a tab. However, you can customize the delimiter and adjust the behavior using different options. The paste command is a powerful tool for combining data from multiple sources efficiently. Whether you need to merge files or generate structured output, mastering the paste command can streamline your workflow and simplify data processing tasks.
