Question

I want to split a large collection if text files. This is the script that i currently use

for file in *.txt
do
    split -b 120k "$file" "$file"_
done

When the input file is

hello_world.txt

the splitted files would be

hello_world.txt_AA
hello_world.txt_AB
hello_world.txt_AC

i want it to be like

hello_world_AA
hello_world_AB
hello_world_AC

How do i do it in linux ?

Answer 1

In bash, an expression of the form

${variable%suffix}

will expand to the contents of variable with the suffix removed from the end.

You can use this when you specify the new file prefix to split like this:

for file in *.txt
do
    split -b 120k "$file" "${file%.txt}"_
done
