Problem with RDD bash script variable

I have the folowing bash script i'm trying to implement, but it fails awfully, can anyone help me with some advice...

#!/bin/bash
FILE='/var/www/router.rrd'
OUTPUT='/var/www/router.png'
RRDTOOL='rrdtool graph'
$RRDTOOL $OUTPUT \
        -t "192.168.10.1" -v "Time in ms" \
        --start="now-1d" \
        --end="now" \
        --height="120" \
        --width="开发者_如何学Python440" \
        "DEF:ping_time=$FILE:ping:AVERAGE" \
        "CDEF:shading2=ping_time,0.98,*" "AREA:shading2#F90000:router" \
        "GPRINT:ping_time:LAST:Last\: %5.2lf ms" \
        "GPRINT:ping_time:MIN:Min\: %5.2lf ms" \
        "GPRINT:ping_time:MAX:Max\: %5.2lf ms" \
        "GPRINT:ping_time:AVERAGE:Avg\: %5.2lf ms" >/dev/null

hostname:/# sh -v /var/www/router.sh
FILE='/var/www/router.rrd'
OUTPUT='/var/www/router.png'
RRDTOOL='rrdtool graph'
HOST='hello'

"$RRDTOOL" $OUTPUT \
: command not foundre_retea/ping/router.sh: line 7: rrdtool graph

        "GPRINT:ping_time:LAST:Last\: %5.2lf ms" \
.... and so on

My first guess is that it gives you an error that says "command not found". If that's the case it's because you're putting a command and an argument in a variable. Don't do that. Please see BashFAQ/050.

Additionally, it looks like your script file may have Windows line endings. If that's the case then running dos2unix on it will fix that.

dos2unix scriptname

Another possibility is that you may have white space after your line-continuation backslashes. Removing the white space characters may help:

sed 's/\\[[:blank:]]\+$/\\/' scriptname
