Hi Jan,
I think this is the second time I've seen you mention the format of the
index.txt file... so it seems you're "mistakenly" trying to parse
index.txt to get the file/path names of the stuff you need to download.
(pardon me if my mind reading skills are slightly off)
-----------------------------------------------------------
#!/bin/ksh
ftp_host="ftp.openbsd.org"
basepath="pub/OpenBSD/snapshots"
arch=`uname -m`
ftp -i -n <<EOF >>ftp.log
open $ftp_host
user anonymous none@
nlist $basepath/$arch ftp.files
EOF
# exclude floppy*.fs and *.iso
for FNAME in `grep -v -e "\.iso" -e "\.fs" ftp.files |
sed -e "s:$basepath/$arch/::"`; do
if [[ -z $FLIST ]]; then
FLIST="$FNAME";
else
FLIST="$FLIST FNAME"
fi
done
-----------------------------------------------------------
NOTE the "for ..." is wrapped,
The result is $FLIST contains just a list of all the file names of the
stuff on the ftp server in the given directory excluding the *.fs and
*.iso files.
The real magic in the above is in the "nlist" command of ftp, and you
don't necessarily need to do it in a shell script. perl would work
equally well.
If my mind reading skills are off, and you're trying to check the time
stamp of files on the ftp server, then check out the ftp "modtime"
command, and point it at the SHA256 file (that "should" be there).
In other words, the format of "index.txt" should not matter since there
are better ways to get the information you want.
