Please help me regarding the bash script

nareshreddyn · 08-31-2018, 07:12 AM

#!/bin/bash

echo "#################################################################"
echo "Unzip the Patch Files and Move to the Patch Home" >> ${LOG_FILE}
echo "#################################################################"
ssh ${appUsr}@${adminHost} "cd ${BINARIES_HOME}; find . -type f -mmin -120 -name '*.zip' -exec sh -c 'unzip -qd "`dirname "{}"`" "{}"' ';'; var=$(ls | grep -E '^[0-9]+$'); mv $var $PATCH_HOME;"

This is a part of a script.I can login to the adminhost and able to unzip the file.But unable to store the output in var. Any suggestions.

Below is the error i am getting
mv: missing destination file operand after `/opt/oracle/weblogic/12.2/OPatch'
Try `mv --help' for more information.
++ sleep 10

Any suggestions.Thanks a million in advance.

Please see the link in my signature about how to use CODE tags to enclose your script in them and have it appear as code.

Do you see the complaint?

This is telling you where the error is located. You do not have a destination file for your mv command. It would appear that you either do not have a valid $PATCH_HOME variable or valid $var variable.

Since your comment was that it did not store it in var, then my assumption is that you mean /var, and thus that part of your script should not say $var, but instead /var

Hi,

Thanks for the update.$PATCH_HOME is available which is /opt/oracle/weblogic/12.2/OPatch. Here the problem is var is not storing the grep value.I tried different way which is working fine. I need to write the script in one line.

Here is the updated script which worked fine.

Quote:

ssh ${appUsr}@${adminHost} "cd ${BINARIES_HOME}; find . -type f -mmin -10 -name '*.zip' -exec sh -c 'unzip -qd "`dirname "{}"`" "{}"' ';';" >> ${LOG_FILE}
var=$(ssh ${appUsr}@${adminHost} "cd ${BINARIES_HOME}; ls | grep -E '^[0-9]+$'") >> ${LOG_FILE}
echo "$var" >> ${LOG_FILE}

ssh ${appUsr}@${adminHost} "mv ${BINARIES_HOME}/$var $PATCH_HOME;" >> ${LOG_FILE}

Please suggest.

Far as I know, you do something like the following notation:

Code:

$ ssh <user@host> << EOF
    command;
    command;
    command;
EOF

Give that notation a try. I've used it to inject multiple commands to fdisk, but haven't tried it with other commands.
