Shell Programming and Scripting

Hi Guru's,

I 'm trying to execute the below given script in Unix. I am having an issue with the script. The output of the script is given below:

#!/bin/bash


File_Home="/home/essftp/Risk"

cd /home/essftp/Risk
rm -f FileList
rm -f credit_risk*

file1=`ls -lt /export/archives/datman/prod/bloomberg/credit_risk.out.gz* |awk '{print $9 "\t" $10}'|cut -f5 -d"/"|head -1`
sftp nydbrsko@eqdmnypr1<<END_SCRIPT >&FileList
cd /export/archives/datman/prod/bloomberg
ls credit_risk.out.gz*
bye
END_SCRIPT

filename=`nawk '{if($NF ~ "credit_risk.out.gz") {print $NF}}' FileList | sort -r | sed -ne '1p'`

ftp nydbrsko@eqdmnypr1<<END_SCRIPT
cd /export/archives/datman/prod/bloomberg
get $filename
bye
END_SCRIPT

echo "/home/essftp/Risk/$filename"

mv $file_name /home/essftp/Risk/credit_risk.out.gz
gunzip -f credit_risk.out.gz
chmod 777 credit_risk.out
echo "DONE"


Script Output:

/export/archives/datman/prod/bloomberg/credit_risk.out.gz*: No such file or directory
nydbrsko's Password:
nydbrsko@eqdmnypr1: unknown host or invalid literal address

/home/essftp/Risk/credit_risk.out.gz.20090412
mv: Insufficient arguments (1)
Usage: mv [-f] [-i] f1 f2
mv [-f] [-i] f1 ... fn d1
mv [-f] [-i] d1 d2
gunzip: credit_risk.out.gz: No such file or directory
chmod: WARNING: can't access credit_risk.out
DONE

The script is logging into sftp site and getting the file name. But in the end it is failing to move the file.

Can someone please look into this and explain me whats wrong am i doing here.

Thanks and Best Regards

Use below option to debug it.
This will might help you.

#!/bin/bash -x

Is there a "mv $file_name " or "mv $filename" also maybe put in the path?

variable misname, giannicello.
remove the underscore in the mv file_name command to be mv filename

Code:

filename=`nawk '{
  if($NF ~ "credit_risk.out.gz") {print $NF}}' FileList | sort -r | sed -ne '1p'`

ftp nydbrsko@eqdmnypr1<<END_SCRIPT
cd /export/archives/datman/prod/bloomberg
get $filename
bye
END_SCRIPT

echo "/home/essftp/Risk/$filename"

mv $filename /home/essftp/Risk/credit_risk.out.gz

oh and add this after the nawk statement:

Code:

if [ -z "$filename" ]; then
  echo no credit_risk.out.gz found.
  exit 1
fi

( could be done a little nicer with variable file name.... )
