How to check file exists via Bash script?

Question

I'm trying to clone a repo and test it after is done via bash script. I have written my test code based on Bash Shell: Check File Exists or Not.

#!/bin/bash

echo "*** TRY TO INIT INFER ***"

# Clone Infer
INFER_GIT_PATH="https://github.com/facebook/infer.git"
echo "> Try to Clone Infer from ${INFER_GIT_PATH}"
git clone ${INFER_GIT_PATH}

INFER_PATH="/infer/infer/bin/infer"
[ -e ${INFER_PATH} ] && echo "Infer downloaded successfully" || echo "Something went wrong :("

Although repo can be downloaded successfully and /infer/infer/bin/infer.sh exists, I'm always getting Something went wrong :( message.

Change it to this (use a relative path):

INFER_PATH="./infer/infer/bin/infer"
[ -e ${INFER_PATH} ] && echo "Infer downloaded successfully" || echo "Something went wrong :("

and it should work.

That line was my mistake, I just updated my code. Thanks for pointing out but I still have same output :(

so the name of your file is infer or infer.sh?

I updated my comment. You have to use a relative path.

If you want to know if a file exist, you can use -f flag:

[ -f /infer/infer/bin/infer ] && echo "Infer downloaded successfully" || echo "Something went wrong :("
