Hi,

I am trying to read a file line-by-line in a while loop, and perform some tasks which involves non-interactive SSH to a remote server. The code looks something like this --

Code:

#!/usr/bin/ksh

export myFile=/path/to/my/file.load
while read line
do

do something

## Adding the SSH key for non-interactive ssh
export DISPLAY=junk
export SSH_ASKPASS=/home/subu/add-passphrase.ksh
eval `/usr/bin/ssh-agent | tee -a /tmp/pid.$$.txt`
ssh-add < /dev/null

ssh remoteHost "
if [[ -s someFile ]]
then
ftp -nv myHost << EOF > /dev/null 2>&1
user usrName pwd
prompt
put someFile
bye
EOF
rm -f someFile"

do something else
done < ${myFile}

The problem is after executing the 1st run of the loop perfectly, the read of the while is just not able to read from the file that I've provided as an input to it. Is it happening because of the

Code:

ssh-add < /dev/null

part or the here-doc in the ftp part? Is there an alternate way to do this?

I running this script using KSH in a Solaris box. When I run it using set -x option, the output that I get is

Code:

0< line.from.myFile
read line
.
.
.
.
read line

There is no '0< next.line.from.myFile' before the last 'read line'. This prompts me to conclude that ${myFile} is no longer attached to STDIN, and hence the read fails.
