How to test for if two files exist?

Question

I would like to check if both files exist, but I am getting

test.sh: line 3: [: missing `]\'

Can anyone see what\'s wrong?

#!/b         


        

Answer 1

if [ -e .ssh/id_rsa -a -e .ssh/id_rsa.pub ]; then
 echo "both exist"
else
 echo "one or more is missing"
fi

Here,

-e check only the file is exits or not.If exits,it return true.else,it return false.

-f also do the same thing but,it check whether the given file is regular file or not.based on that it return the true/false.

Then you are using &&.So that,It need two [[ .. ]] brackets to execute.

instead you can use the -a [same as && operator] -o [same as || operator]. If you need more information go through this link
