BASH: How to copy the name of the file and insert it into the text using script?

So I need to create a lot of text files.

Each of the text file is named AAAAA.txt, BBBBB.txt, CCCCC.txt and etc etc. Within each text file, all the content is as follows:

1.Copy “to-be-replaced”.txt into the folder EXCLUSIVE.

2.Copy the gs file to replace the existing gs file.

3.The .projectdata should also be copied to the correct path.

So, I need to write a script, that copies the name of the file (AAAAA, BBBBB, and so on) and then place it in the “to-be-replaced” within its content.

How can I do that? need some idea please.

Thank you~~ MT32

Answer

Use a HERE document which expands variables if the delimiter isn’t quoted:

#!/bin/bash
for char in {A..Z} ; do
    filename=$char$char$char$char$char.txt
    cat <<EOF > $filename
1.Copy $filename into the folder EXCLUSIVE.

2.Copy the gs file to replace the existing gs file.

3.The .projectdata should also be copied to the correct path.

EOF
done
