Re: Oddity...losing filename from stdin

I notice that you're piping the output of ls... are you doing this in the directory where saveme is located? If not, ls will produce no output (but an error message on STDERR). Are you sure that ls is producing what you think it is? Maybe you could try using echo "saveme" instead?

Good question. In fact, I am in the right directory. I've even checked to make sure that the file is there. `$ ls -l saveme -rw-r--r-- 1 jconner jconner 0 04-09 12:07 saveme` [download] I also decided to check a few more ways and found that the first file is getting skipped! Very wierd. I've never seen this before. `$ ls saveme .vimrc \| perl -n -e ' print <>,"\n";' saveme $ ls saveme .vimrc \| perl -n -e ' >while (<> ) { > print $_,"\n"; >} >' saveme` [download] Notice in these examples that I gave ls two files to query and this it should be that ls pipes out the two files to the perl one-liner. Btw, I double-checked that .vimrc exists too. :) `$ ls -l .vimrc -rw-r--r-- 1 jconner jconner 831 01-18 17:55 .vimrc` [download] _ _ _ _ _ _ _ _ _ _ - Jim Insert clever comment here...

$ ls saveme .vimrc | perl -n -e '

saveme

$ ls saveme .vimrc | perl -n -e '
