Hi.  I've got two related questions:

1.  I would like to use the find command to return a list of files
without the paths attached, i.e., it would just return the file names.

2. Given a variable that contains a list of path/file names, I'd like
to be able to save the string in another variable but with the paths
stripped off.

Thanks for any input!

If you use GNU find, then look closer at -printf option. Otherwise you
could use sed for removing directories.

Use sed.

    var1=$(find -type f)
    echo "$var1"
    var2=$(echo "$var1" | perl -F/ -alne 'print $F[-1]')
    echo "$var2"
#or
    var3=$(echo "$var1" | awk -F/ '{print $NF}')
    echo "$var3"
#(under GNU bash)

find . -exec basename {} \;

Or, probably more efficient but less readable:

find .//. -print | awk '
  /\/\// && NR > 1 {
    sub(/.*\//, "", file)
    print file
    file = $0
    next
  }
  {file = file "\n" $0}
  END {
    if (NR > 0) {
      sub(/.*\//, "", file)
      print file
    }
  }'

How can a variable contain a list of paths? What would you use
as a separator given that every character accepted in a shell
variable is also allowed in a file path (except for zsh that
accepts the NUL character in its variables), you'd need a way to
escape the separator.

Maybe you're thinking of an array variable. But beware that
arrays are a non standard feature.

What can be done is to have the variable written in the xargs
input format (where backslash can be used to escape the
separators), such as:

var='a/file1 b/file2
c/file\ 3
d/file\
4'

Then, you can do:

printf '%s\n' "$var" | xargs -n1 basename
