Prompt the user to enter a file name to check

read -p "Enter a file name to check: " myfile

Check if the file exists and is not empty

if [ -n "$(find . -maxdepth 1 -type f -name "${myfile}" -print -quit)" ]; then ## Find the actual file with the given name pattern actual_file=$(find . -maxdepth 1 -type f -name "${myfile}" -print -quit) ## Check if the file is not empty if [ -s "$actual_file" ]; then ## Print a message indicating the file is not empty echo "$actual_file is not empty" ## Print the contents of the file echo "Contents of $actual_file:" cat "$actual_file" else ## Print a message indicating the file is empty echo "$actual_file is empty" fi else ## Print a message indicating the file does not exist echo "$myfile does not exist" fi

Line 1 Explanation:

if [ -n "$(find . -maxdepth 1 -type f -name "${myfile}" -print -quit)" ]; then [ -n "$(find . -maxdepth 1 -type f -name "${myfile}" -print -quit)" ]: Tests whether the output of the find command is non-empty. find . -maxdepth 1 -type f -name "${myfile}" -print -quit: Searches for files in the current directory (.) matching the pattern ${myfile}. -maxdepth 1: Limits the search to the current directory only. -type f: Specifies that only files should be considered (not directories). -name "${myfile}*": Matches files whose names start with ${myfile}. -print -quit: Prints the name of the first match and then quits the search. -n: Checks if the output of the find command is non-empty. Line 2 Explanation:

actual_file=$(find . -maxdepth 1 -type f -name "${myfile}" -print -quit) actual_file=: Assigns the result of the find command to the variable actual_file. $(find . -maxdepth 1 -type f -name "${myfile}" -print -quit): Executes the find command, which searches for files matching the pattern ${myfile}* and prints the name of the first match before quitting.
