Hi
I am working on a program that i should use sh type script, now i have bash script , so how can i change bash script to sh?
i would appreciate if someone could help me to convert,
the script is :

PHP Code:



#!/bin/bash 
rOut=/var/spool/asterisk/outgoing/ 
rUser=asterisk 
rGroup=asterisk 
nFile=call.csv 
rtry=5 
mtry=3 
stime=60 
 
for nums in $(cat $nFile) 
    do 
        num=`echo $nums | awk -F"," {'print $1'}` 
        noise=`echo $nums | awk -F"," {'print $2'}` 
        nTrunk=`echo $nums | awk -F"," {'print $4'}` 
 
echo "`date`,$num,$noise" >> call-log.csv 
echo "Channel: DAHDI/g2/$num" >> $num.call 
echo "RetryTime:$rtry" >> $num.call 
echo "MaxRetries:$mtry" >> $num.call 
echo "Context: campain" >> $num.call 
echo "CallerID: $num" >> $num.call 
echo "Extension: 300"  >> $num.call 
 
chown $rUser.$rGroup $num.call 
mv $num.call $rOut 
sleep $stime 
done

Code:

awk d=`date` -F"'" {
print $d, $1, $2 >> call-log.csv; 
print "Channel: DAHDI/g2/" $1" >> $1.call

and so on. ie a single awk without too many variables loops, 3 awks for each line which is in a for loop etc.

1) at first line, use "#!/bin/sh" instead of "#!/bin/bas

2) try to run your script, when error occurs, fix it.

3) can use "-x" option "#!/bin/sh -x", so can get more debug information

4) can man sh to get more help (sh = bash --posix)

hope these information above are helpful for you.
