In Unix, how do I combine several text files into a single file?
In Unix, to combine several text files into a single file,
use the cat command:
cat file1 file2 file3 > newfile
Replace file1, file2, and file3
with the names of the files you wish to combine, in the order you want
them to appear in the combined document. Replace newfile
with a name for your newly combined single file.
If you want to add one or more files to an existing document, use the
format:
cat file1 file2 file3 >> destfile
This command will add file1, file2, and
file3 (in that order) to the end of
destfile.
Note: If you use > instead of
>>, you will overwrite destfile rather
than add to it.
At Indiana University, to get support for personal or departmental Linux or Unix systems, see At IU, how do I get support for Linux or Unix?
