bash clear file if exists

Answer 1

file="/path/to/file"
if [ -f $file ]; then
    rm $file
fi

In variable file are path to file what you want to delete.

Don't bother checking if the file exists, just try to remove it:

rm -f /path/file

or

rm /path/file 2> /dev/null

Another one line command:

[ -e file ] && rm file
