Subject: [zftp] zfcd completion and FTP ls behavior
Date: Fri, 15 Aug 2008 16:07:03 +0100 [thread overview]
Message-ID: <20080815150703.GB5278@sc.homeunix.net> (raw)
Hiya,
A FTP site (ftpperso.free.fr) outputs a ls -l type long listing
upon the "ls" FTP command.
So this code in zfcd_match:
# If we're using -F, we get away with using a directory
# to list, but not a glob. Don't ask me why.
# I hate having to rely on awk here.
zftp ls -LF $dir >$tmpf
reply=($(awk '/\/$/ { print substr($1, 1, length($1)-1) }' $tmpf))
rm -f $tmpf
returns the "drwxr-xr-"s instead of the directory names.
Also, why using a tmpfile? Why awk? Why $1?
Is the tempfile to avoid the fork so that because zftp ls
updates a cache?
On that particular FTP server, using ls -1LF fixes it except for
filenames with blanks.
So:
reply=(${(f)"$(zftp ls -1LF $dir | sed -n 's|\(.*\)/$|\1|p')"})
would do.
or:
reply=(${${(M)${(f)"$(zftp ls -1LF $dir)"}#*/}%/})
Or with a temp file:
local tmpf==(:)
zftp ls -1LF $dir > $tmpf
reply=(${(f)"$(sed -n 's|\(.*\)/$|\1|p' < $tmp)"})
rm -f $tmpf
There's a similar problem in zfget_match.
