Question

I’m trying to combine some text to a variable and output the value of the combined variable. For example:

testFILE=/tmp/some_file.log
function test_param {
echo $1
echo test$1
echo $(test$1) #this is where I want to output the value of the combined variable
}

test_param FILE

Output would be:

FILE
testFILE
/tmp/some_file.log  <-- this is what I can't figure out.

Any ideas?

If I’m not using the correct terminology please correct me.

Thanks,
Jared

do you mean this:

#!/bin/bash

testFILE=/tmp/some_file.log
function test_param {
echo $1
echo test$1
eval "echo \$test$1"
}

test_param FILE

output:

FILE
testFILE
/tmp/some_file.log
