How can I handle a list of files containing spaces in their names on Unix?

Question

I am trying to list files in a directory and do something for them at the Mac OS X prompt.

It should look like this: for f in $ (ls -1); do echo $ f; done

If I have files without spaces in their names (fileA.txt, fileB.txt), the echo works fine. If the files contain spaces in their names ("A.txt file", "B.txt file"), I get 4 lines (file, A.txt, file, B.txt).

I tried using the enumeration command, but that only changed the problem.

If I do this: for f in $ (ls -1); do echo $ f; done I get: file A.txt \ nfile B.txt

(It displays correctly, but it is one line, and I need two lines.

Answer 1

Keep up with ls, if at all possible. Use find from findutils package.

find /target/path -type f -print0 | xargs -0 your_command_here

-print0will force find to output names separated by NUL characters (ASCII zero). The argument -0for xargs suggests that it expects arguments separated by NUL characters, so everything will work fine.

Replace /target/pathwith the path where your files are.

-type fwill only detect files. Use -type dfor directories or omit completely to get both.

your_command_here , . (. , echo _, - , xargs .)

: ( xargs),

find /target/path -type f -exec your_command_here \{\} \;

\{\} \; - escape {} ;, . find your_command_here {} ; , your_command_here find, , .

, find . xargs , , . xargs, .
