Bash - join multiple files

In this article, we would like to show you how to join multiple files using Bash.

Quick solution:

cat file_1.txt file_2.txt file_3.txt > output.txt

Alternative solution

In this section we join multiple files using cat command to read files contents one by one and >> operator to write out them. It is good to prepare place for merged file, so rm command is used also.

Practical example:

rm "/path/to/output.txt"

cat "/path/to/file_1.txt" >> "/path/to/output.txt"
cat "/path/to/file_2.txt" >> "/path/to/output.txt"
cat "/path/to/file_3.txt" >> "/path/to/output.txt"
