Bash script that checks if a file exists in a specific directory

Here are the simple steps to check if a file exists in a specific directory using Bash script in linux.

1. Create a new file as mentioned below.

vi script_name.sh

2. Copy and paste below simple Bash script that checks if a file exists in a specific directory:

#!/bin/bash


# Specify the directory path and the file name to be checked

directory="/path/to/your/directory"

file_name="yourfile.txt"

# Check if the file exists in the specified directory

if [ -e "$directory/$file_name" ]; then

echo "The file $file_name exists in $directory."

else

echo "The file $file_name does not exist in $directory."

fi

Note : Replace “/path/to/your/directory” with the actual path of the directory you want to check and “yourfile.txt” with the name of the file you want to verify the existence of.

Here’s a breakdown of the script:

#!/bin/bash : This line specifies the Bash interpreter.

directory =”/path/to/your/directory” : Sets the directory path.

file_name=”yourfile.txt” : Sets the name of the file to be checked.

if [ -e “$directory/$file_name” ]; then : Checks if the file exists in the specified directory.

echo “The file $file_name exists in $directory.” : Prints a message indicating that the file exists.

else : Indicates the start of the code block to be executed if the file does not exist.

echo “The file $file_name does not exist in $directory.” : Prints a message indicating that the file does not exist.

3. Save and close the “vi” editor by pressing “Esc” key and type :wq!

4. Make sure to give execute permissions to the script before running it. You can do this by running the following command in the terminal:

chmod +x script_name.sh

Note : Replace “script_name.sh” with the actual name you save the script as.
