How to Check If A File Exists or Not in Bash Script

You can use if condition in bash script to do that. If conditions takes ‘-f’ to test if a file exists or not. Syntax would be the following:

$FILE = $1
if [ -f $FILE ]; then
echo "File Exists"
else
echo "File Do Not Exist"
endif

Now, if your script only demands to check if the file do not exist, you can use a unary operator for negate the boolean value as following:

$FILE = $1
if[ ! -f $FILE ]; then
echo "File Do Not Exist"
endif
