how to set umask for directory and exit places

Question

I am writing a script which is creating directories to be used using the following command mktemp -d

I've to add a umask to the directories being created in the above way. And I've to add it to the exit conditions of the code.

Below is the sample code:

DIR1=$(mktemp -d)

wget_output=$(wget -q -P "$DIR1" "$CERT1")
    if [ $? -ne 0 ]; then
        echo "Certificates NOT Found OR Saving the certificates in directory failed."
        exit
    fi

How to do it?

I've found the solution.

In the begining of the file record original umask

umask=$(umask)

then set the value before the directory creation.

umask 077
DIR1=$(mktemp -d)

wget_output=$(wget -q -P "$DIR1" "$CERT1")
    if [ $? -ne 0 ]; then
        echo "Certificates NOT Found OR Saving the certificates in directory failed."
        exit
    fi

then in the end restore umask using

umask ${umask}

So, the updated code becomes:

umask=$(umask) #record umask
.
.
.
umask 077 # set umask value
DIR1=$(mktemp -d)

wget_output=$(wget -q -P "$DIR1" "$CERT1")
    if [ $? -ne 0 ]; then
        echo "Certificates NOT Found OR Saving the certificates in directory failed."
        exit
    fi

umask ${umask} # restore umask
