Have many text documents saved and want them to print them as one doc?
$ ls *.txt
file1.txt file2.txt file3.txt file4.txt file5.txt
Use cat:
$ cat file1.txt file2.txt file3.txt file4.txt file5.txt > bigfile.txt
Or you can use a for loop:
$ for i in *.txt; do cat "$i" >> bigfile.txt; done
$ ls *.txt
bigfile.txt file1.txt file2.txt file3.txt file4.txt file5.txt
