How to create folder by using if and elif condition?
Hi All,
I have already code to create folder for one country let say US , now we want to create folder/directory for JP country also using shell script , application server.
Code:
$COUNTRY='US'
if [[ $COUNTRY_CODE = "US" ]]
then
if mkdir -m 777 -p /opt/TEST/$COUNTRY/$INVOICE >/dev/null 2>&1 | tee -a ${LOG_FILE_NAME}
then
echo "Directory Structure Created Successfully." | tee -a ${LOG_FILE_NAME}
else
echo "Directory not created "| tee -a $LOG_FILE_NAME
exit 2
fi
fi
$COUNTRY='JP'
if [[ $COUNTRY_CODE = "JP" ]]
then
if mkdir -m 777 -p /opt/TEST/$COUNTRY/$INVOICE >/dev/null 2>&1 | tee -a ${LOG_FILE_NAME}
then
echo "Directory Structure Created Successfully." | tee -a ${LOG_FILE_NAME}
else
echo "Directory not created "| tee -a $LOG_FILE_NAME
exit 2
fi
fi
I can use same code as like US , but i need to use the code in one line of could you pls help me on this
The $ is not needed and is not allowed when you are assigning a value to a variable.
Code:
$COUNTRY="some country code"
is a syntax error. Presumably, you want:
Code:
COUNTRY="some country code"
instead.
Why do you set COUNTRY and check COUNTRY_CODE? You need to pick one variable name and use it consistently.
Why do you set a variable on one line and then think you need to test to see if that variable has been set to the value you just assigned to it on the next line?
Is there some reason why only two countries should be allowed by your script? Why is the test needed at all? Do you just need a test to verify that COUNTRY has been assigned a value that is not the empty string?
If you want to get a country code, verify that it is JP or US and create the directory only if it is one of those two country codes, you could try something more like:
Code:
printf 'Enter country code: '
read -r COUNTRY
if [ "$COUNTRY" = "JP" ] || [ "$COUNTRY" = "US" ]
then
if mkdir -m 777 -p "/opt/TEST/$COUNTRY/$INVOICE" >/dev/null 2>&1 | tee -a "${LOG_FILE_NAME}"
then
echo 'Directory Structure Created Successfully.' | tee -a "${LOG_FILE_NAME}"
else
echo 'Directory not created' | tee -a "$LOG_FILE_NAME"
exit 1
fi
else
echo "Unexpected country code '$COUNTRY' specified; Directory not created" | tee -a "$LOG_FILE_NAME"
exit 2
fi
but, of course, none of this works unless something you haven't shown us assigns appropriate values to the variables INVOICE and LOG_FILE_NAME. And, since you haven't told us what shell you're using, I can't make any guarantee that any of this will work.

Reason: Numbered list not working with embedded CODE.
I'm pretty sure that piping mkdir's output through tee will (almost) always succeed, so "directory not created" will never happen (unless tee fails for some reason):
Code:
if mkdir /XX | tee YY ; then echo good; else echo bad; fi
mkdir: cannot create directory ‘/XX’: Permission denied
good
RudiC is correct... And, in addition to that, redirecting output to /dev/null (even though mkdir never writes anything to standard output) and then redirecting standard error to standard output throws away any diagnostic messages that mkdir might produce. But, you should be able to change:
Code:
if mkdir -m 777 -p "/opt/TEST/$COUNTRY/$INVOICE" >/dev/null 2>&1 | tee -a "${LOG_FILE_NAME}"
to:
Code:
mkdir -m 777 -p "/opt/TEST/$COUNTRY/$INVOICE" 2>&1 | tee -a "${LOG_FILE_NAME}"
if [ -d "/opt/TEST/$COUNTRY/$INVOICE" ]
to get what you want. Note, however, that if the directory already existed, the mkdir will fail, but you still have the directory you want. If you don't want to get EEXIST errors when the directory already exists, you might want to try something more like:
Code:
DIR="/opt/TEST/$COUNTRY/$INVOICE"
[ ! -d "$DIR" ] && mkdir -m 777 -p "$DIR" 2>&1 | tee -a "${LOG_FILE_NAME}"
if [ -d "$DIR" ]
to give you a success message if the directory has been created at some point in the past or during the execution of your script and the desired error messages if you didn't successfully create the desired directory.
The -p option to mkdir will make it "not fail" on existing directories, so sth serious must happen to select the failure branch.
Serious, yes. Unusual, no. Unlikely, maybe not. If the directory in which a new directory is to be created is not writeable by the user running the script, mkdir -p will fail with an EPERM error. If a non-directory (or symbolic link pointing to a non-directory) file exists with the name of a directory to be created, mkdir -p will fail with an EEXIST error. And, of course, EACCES, ELOOP, EMLINK, ENAMETOOLONG, ENOSPC, ENOTDIR, and EROFS errors are also possible.
