I store a list of files in a text file (test.txt) on Windows XP.
I want to use the list of files and process it (e.g. ls).
What is the command to do that?
I tried the following commands but to no avail.
$ cat test.txt
test.txt
$ cat test.txt | xargs ls
: No such file or directory
$ cat test.txt | xargs -delimiter="\n" ls
xargs: Invalid input delimiter specification elimiter=\n: the delimiter must be
either a single char
acter or an escape sequence starting with \.
$ cat test.txt | xargs -delimiter='\n' ls
xargs: Invalid input delimiter specification elimiter=\n: the delimiter must be
either a single char
acter or an escape sequence starting with \.
$ cat test.txt | xargs -delimiter='\\n' ls
xargs: Invalid input delimiter specification elimiter=\\n: the delimiter must be
either a single cha
racter or an escape sequence starting with \.
$ cat test.txt | xargs -delimiter="\\n" ls
xargs: Invalid input delimiter specification elimiter=\n: the delimiter must be

I would also suggest that you check your filenames in test.txt to make
sure, if you included paths, that they are absolute and follow the
Cygwin virtual-paths (cygpath) syntax, i.e.: /cygdrive/c/... or
/etc/share/... and so on. Barring that, a path in Unix notation relative
to your $PWD -- or the directory where test.txt is saved -- is a good
starting point (npi): something along the lines of bin/deprecated or
../man1 .
I know one of the trip-ups I often have if I spend any time away from a
L/Unix environment has to do with the "mv" command: I often forget that
it prefers absolute paths from root folders (or in the case of Cygwin,
virtual ones taken as real) or dot-dot-slash relative path syntax to
just "/god-directory/" or what-have-you. Many other commands,
particularly ls and ln -s, are likewise "particular about their paths."
