Re: Redirecting lftp's output to my application's input with a pipe

There is no output on stdout (the one you connected via the pipe) but
only on stderr (logging in; negotiation; putting and stuff).

        #!/bin/bash

        set -e

        TARGET=cfengine

        OUTPUT=`lftp -c "\
        set dns:fatal-timeout 30;\
        set net:timeout 30;\
        set net:max-retries 1;\
        set cmd:fail-exit true;\
        open ${TARGET}; \
        cls \
        ;" 2> /dev/null`

        export LDIR='/home/cip/adm/sithglan/work/monitor-ftp/listings'

        if [ -z "${OUTPUT}" ]; then
                exit;
        fi

        echo "${OUTPUT}" >  $LDIR/.$TARGET.listing

        if cmp -s $LDIR/.$TARGET.listing $LDIR/$TARGET.listing; then
                rm $LDIR/.$TARGET.listing
        else
                (diff -u $LDIR/$TARGET.listing $LDIR/.$TARGET.listing | egrep 
'^[+-][^-]') || /bin/true
                echo
                mv $LDIR/.$TARGET.listing $LDIR/$TARGET.listing
        fi

I attached this recipie because it has some good defaults for automated
lftp stuff. When a ftp site is down lftp would normally try forever to
connect to it, until it is killed. With this settings it gives up after
30 seconds or so.

Gruesse,
