Question

The title is rather more simplified than the functionality I am trying to express in a script.

I have a one-level deep directory tree (much bigger than example) which contain various content, although only two particular files are of interest to me. A file called ‘current’ and another called ‘revisions’

- foo    |    |-> current  - bar    |    |-> current    |-> revisions  - baz    |    |-> not-affected 

The script in mind would be triggered from the parent directory to foo/bar/baz and it would perform the following

1. Scan all subdirectories

2. When it finds a directory containing ‘current’ it will

   3. Append the content of ‘current’ onto revisions ‘cat ${pwd}/current >> ${pwd}/revisions ‘
3. Directories not containing a file named ‘current’ are to remain unaffected

Answer 1

If it’s one level deep, this should work:

for c in */current; do cat ${c} >> ${c%%current}revisions; done
