I have some set of files with character strings in lines such that there is a folder containing
file1
file2
file3
and within those files there a variable length lists of strings of characters such that file 1 may read
file1.itemA
file1.itemB
file1.itemC
While file 2 may only contain
file2.itemA
file2.itemB
I want to add a file specific code to every line within each file such that
code1.file1.itemA
code1.file1.itemB
code1.file1.itemC
And
code2.file2.itemA
code2.file2.itemB
How can I do this within unix? I am using the OSX terminal to execute commands.
I'm not near a terminal to test, but, how about:
cd /path/to/your/files
word='code'
base=1
for file in *; do sed -i -e "s/^/$word$base/" "${file}"; base=$(( $base + 1 )); done
The $word variable is the constant you want. The $base variable holds the count that is incremented on each file, initially set to 1.
