Given a file path (e.g. /src/com/mot), how can I check whether mot exists, and create it if it doesn't using Linux or shell scripting??

Checking If a Directory Exists In a Bash Shell Script-h "/path/to/dir" ] && echo "Directory /path/to/dir exists." || echo "Error: Directory /path/to/dir exists but point to $(readlink -f /path/to/dir)." The cmd2 is executed if, and only if, cmd1 returns a non-zero exit status.
To see them in the terminal, you use the "ls" command, which is used to list files and directories. So, when I type "ls" and press "Enter" we see the same folders that we do in the Finder window.
The fsck utility makes it easy for us to recover the lost data. To recover lost data, we need to have run fsck before. Most Linux distros would run the fsck command on boot if the machine didn't properly shut down. Otherwise, we'll have to run it manually.
The ls command is used to list files or directories in Linux and other Unix-based operating systems. Just like you navigate in your File explorer or Finder with a GUI, the ls command allows you to list all files or directories in the current directory by default, and further interact with them via the command line.
With bash/sh/ksh, you can do:
if [ ! -d /directory/to/check ]; then mkdir -p /directory/toc/check fi For files, replace -d with -f, then you can do whatever operations you need on the non-existant file.
