I’ve used the following script to see if a file exists:
#!/bin/bash FILE=$1 if [ -f $FILE ]; then echo "File $FILE exists." else echo "File $FILE does not exist." fi
What’s the correct syntax to use if I only want to check if the file does not exist?
#!/bin/bash FILE=$1 if [ $FILE does not exist ]; then echo "File $FILE does not exist." fi
The test command (
[ here) has a “not” logical operator which is the exclamation point (similar to many other languages). Try this:
if [ ! -f /tmp/foo.txt ]; then echo "File not found!" fi
