makefile: how to add a prefix to the basename?

I have a lit of files (which I get from find bla -name "*.so") such as:

/bla/a1.so
/bla/a2.so
/bla/blo/a3.so
/bla/blo/a4.so
/bla/blo/bli/a5.so

and I want to rename them such as it becomes:

/bla/liba1.so
/bla/liba2.so
/bla/blo/liba3.so
/bla/blo/liba4.so
/bla/blo/bli/liba5.so

… i.e. add the prefix ‘lib’ to the basename

any idea on how to do that in bash ?

Answer 1

Something along the lines of:

for a in /bla/a1.so /bla/a2.so /bla/blo/a4.so
do
  dn=$(dirname $a)
  fn=$(basename $a)
  mv "$a" "${dn}/lib${fn}"
done

should do it. You might want to add code to read the list of filenames from a file, rather than listing them verbatim in the script, of course.
