Test file
Hi,

I try to test 3 files,
Code:
#!/bin/bash
if  [ ! -f "$tf3" -a -f "$tf1" -a -f "$tf2" ];
then
        echo "ok"
else
        echo "ko"

It works partially, but I want that the output tell me "ok" only if the three files doesn't exist. Smilie

If you change:
Code:
if  [ ! -f "$tf3" -a -f "$tf1" -a -f "$tf2" ];

to:
Code:
if [ ! -f "$tf3" -a ! -f "$tf1" -a ! -f "$tf2" ];

it would work on some systems. To work with any bash, the following should work:
Code:
if [ ! -f "$tf3" ] && [ ! -f "$tf1" ] && [ ! -f "$tf2" ]

but ALL of these will still leave you with a syntax error unless you also add another line at the end of your script:
Code:
fi

I have the same problem, If tf3, is missing the output tell me "ok", but I want that when there are three missing files

It reacts like an "OR"

Please look closely at what I suggested in post #2. Note that you need ! -f file for all three tests; while your code only had one exclamation point.

Yes, I modified in :
Code:
if [ ! -f "$tf3" ] && [ ! -f "$tf1" ] && [ ! -f "$tf2" ]
then
echo "ok"
else
echo "ko"
fi

But that's the same, If only tf3 is missing the output told me "ok" then I wish it told "ko"

Maybe the solution is to put tf1,tf2,tf3 in an array and to test the array ? is this the good way?

Please show us how you defined and exported the variables tf1, tf2, and tf3 before executing your if statement!
