Guys,

I have one script it runs fine by itself but behave strangely when run through crontab. This script simply grabs files from one server (using scp) and puts it under some directly on host server.

I exported PATH in script and tried to do same in crontab as well but no luck.

Really appreciate if someone can throw in some ideas on how to fix this?

Thanks
Inder

#!/bin/bash

export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

SrcServer=xyz
Source=a/b/c
File=any
Dest=d/e/f
SrcUsr=usr
SrcPwd=pwd

Timestamp=`date +%Y%m%d_%H%M%S`

cd $Dest

if [ -f $File ];
then
echo "Taking Back up of old file...."
mv $File $File.$Timestamp
fi

cd $Dest

/usr/bin/expect -c "
spawn /usr/bin/scp -pr $SrcUsr@$SrcServer:$Source/$File .
expect {
"*password:*" { send $SrcPwd\r\n; interact }
eof { exit }
}
exit
"
echo "File Transfer Completed..."

insert line: set -xv at the beginning and redirect the output (and stderr) of crontab entry into a file.

I exported the error output and here's what i got

#!/bin/bash


export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
+ export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
+ PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

export PATH
+ export PATH

SrcServer=xyz
+ SrcServer=xyz
Source=a/b/c
+ Source=a/b/c
File=any
+ File=any
Dest=d/e/f
+ Dest=d/e/f
SrcUsr=usr
+ SrcUsr=usr
SrcPwd=pwd
+ SrcPwd=pwd

Timestamp=`date +%Y%m%d_%H%M%S`
date +%Y%m%d_%H%M%S
++ date +%Y%m%d_%H%M%S
+ Timestamp=20120614_165801

cd $Dest
+ cd /home/dest

if [ -f $File ];
then
echo "Taking Back up of old file...."
mv $File $File.$Timestamp
fi
+ '[' -f filename ']'

cd $Dest
+ cd /d/e/f

/usr/bin/expect -c "
spawn /usr/bin/scp -pr $SrcUsr@$SrcServer:$Source/$File .
expect {
"*password:*" { send $SrcPwd\r\n; interact }
eof { exit }
}
exit
"
+ /usr/bin/expect -c '
spawn /usr/bin/scp -pr usr@xyz:/d/e/f/filename .
expect {
*password:* { send pwd\r\n; interact }
eof { exit }
}
exit
'
echo "File Transfer Completed..."
+ echo 'File Transfer Completed...'

any other ideas?

from this log I cannot see anything, it looks like everything is ok. You need to look at the log of expect or log of scp somehow to find out where is the problem
