With the help of BASH shell and IF command, it is possible to find out if a file exists or not on the filesystem. A conditional expression (also know as “evaluating expressions”) can be used by [[ compound command and the test ([) builtin commands to test file attributes and perform string and arithmetic comparisons.
You can easily find out if a regular file does or does not exist in Bash shell under macOS, Linux, FreeBSD, and Unix-like operating system. You can use [ expression ], [[ expression ]], test expression, or if [ expression ]; then .. fi in bash shell along with a !operator. Let us see various ways to find out if a file exists or not in bash shell.

Syntax to find out if file exists with conditional expressions in a Bash Shell

The general syntax is as follows:
[ parameter FILE ]
OR
test parameter FILE
OR
[[ parameter FILE ]]
Where parameter can be any one of the following:

• -e: Returns true value if file exists.
• -f: Return true value if file exists and regular file.
• -r: Return true value if file exists and is readable.
• -w: Return true value if file exists and is writable.
• -x: Return true value if file exists and is executable.
• -d: Return true value if exists and is a directory.

Please note that the [[ works only in Bash, Zsh and the Korn shell, and is more powerful; [ and test are available in POSIX shells. Let us see some examples.

Find out if file /etc/passwd file exist or not

Type the following commands:
$ [ -f /etc/passwd ] && echo 'File exist' || echo 'File does not exist'
$ [ -f /tmp/fileonetwo ] && echo 'File exist' || echo 'File does not exist' Best traktor pro 2 controller ipad.

How can I tell if a regular file named /etc/foo does not exist in Bash?

You can use ! operator as follows:
[ ! -f /etc/foo ] && echo 'File does not exist'Exists
OR

[[ example

Enter the following commands at the shell prompt:
$ [[ -f /etc/passwd ]] && echo 'File exist' || echo 'File does not exist'
$ [[ -f /tmp/fileonetwo ]] && echo 'File exist' || echo 'File does not exist'

Find out if directory /var/logs exist or not

Type the following commands:
$ [ -d /var/logs ] && echo 'Directory exist' || echo 'Directory does not exist'
$ [ -d /dumper/fack ] && echo 'Directory exist' || echo 'Directory does not exist'

[[ example

$ [[ -d /var/logs ]] && echo 'Directory exist' || echo 'Directory does not exist'
$ [[ -d /dumper/fake ]] && echo 'Directory exist' || echo 'Directory does not exist'

Are two files are the same?

Use the -ef primitive with the [[ new test command:

How to check if a file exists in a shell script

You can use conditional expressions in a shell script:

Save and execute the script:
$ chmod +x script.sh
$ ./script.sh /path/to/file
$ ./script.sh /etc/resolv.conf
To check if a file exists in a shell script regardless of type, use the -e option:

You can use this technique to verify that backup directory or backup source directory exits or not in shell scripts. See example script for more information.

Little Snitch offers three features that aren't available in MacOS' built-in ipfw firewall. (It does this by loading a custom kernel module.) Little Snitch allows you to block outgoing connections; the MacOS firewall only blocks incoming connections. Handy if you're running some untrusted program and aren't sure what it's going to do, or if you want to disable a program for updating. Os x firewall vs little snitch.

A complete list for file testing in bash shell

From the test command man page:

[ Expression ]	Meaning
-b filename	Return true if filename is a block special file.
-c filename	Return true if filename exists and is a character special file.
-d filename	Return true filename exists and is a directory.
-e filename	Return true filename exists (regardless of type).
-f filename	Return true filename exists and is a regular file.
-g filename	Return true filename exists and its set group ID flag is set.
-h filename	Return true filename exists and is a symbolic link. This operator is retained for compatibility with previous versions of this program. Do not rely on its existence; use -L instead.
-k filename	Return true filename exists and its sticky bit is set.
-n filename	Return true the length of string is nonzero.
-p filename	Return true filename is a named pipe (FIFO).
-r filename	Return truefilename exists and is readable.
-s filename	Return true filename exists and has a size greater than zero.
-t file_descriptor	Return true the filename whose file descriptor number is file_descriptor is open and is associated with a terminal.
-u filename	Return true filename exists and its set user ID flag is set.
-w filename	Return true filename exists and is writable. True indicates only that the write flag is on. The file is not writable on a read-only file system even if this test indicates true.
-x filename	Return true filename exists and is executable. True indicates only that the execute flag is on. If file is a directory, true indicates that file can be searched.
-z string	Return true the length of string is zero.
-L filename	Return true filename exists and is a symbolic link.
-O filename	Return true filename exists and its owner matches the effective user id of this process.
-G filename	Return true filename exists and its group matches the effective group id of this process.
-S filename	Return true filename exists and is a socket.
file1 -nt file2	True if file1 exists and is newer than file2.
file1 -ot file2	True if file1 exists and is older than file2.
file1 -ef file2	True if file1 and file2 exist and refer to the same file.
