Tree?

[swestrup]

The Linux 'tree' command conveniently outputs a display tree of files and associated data. That's just what I want, only I want to be able to provide my own (potentially very large) list of files. Anyone know how to do that? Tree only seems to accept file names on the command line, and I'll quickly blow through that.

It seems like a job for sort and sed, or possibly a small perl script?

cat <names> | sort | xargs ls -d<flags> | <something that replaces repeated prefixes of the form \/.*\/ with leaders at the start of the line>

Editing the source to take arguments from stdin should be trivial. Are you sure "cat > tree -" doesn't do anything?

Except that it almost certainly drives the indentation state from the recursive directory traversal. Said he without checking.

Yeah, the indentation is probably done recursively. And the

cat > tree -

thing definitely doesn't work. I tried it before posting my question, in case it was an undocumented feature. It looks like I'll have to whip something up out of perl.
