I have a very basic question. I want to run several files in my linux. Name of the files is input1.i, input2.i and so on. After running each input file, I should have an output for each of them. I tried the following method but it failed:

for file in input* do mpiexec -n 6 ./tiger-opt -i file.i # this line runs my inputs done

the error is

Failed to get real path for file.i

I very much appreciate if anyone can help me.

    The -i file.i is taken verbatim. You need to expand your iteration variable like: mpiexec ..... -i "$file" You don't need to add the .i there since it is already taken from input Commented Feb 17, 2022 at 8:14

    Dear @ValentinBajrami, your hint solved my problem. I did it with mpiexec -n 6 ./tiger-opt -i "$file". Do you know how I can make a bash file instead of a for loop? Commented Feb 17, 2022 at 8:37
