For those who are knowledgeable about them let’s get right to it and see how you can quickly do this using your Mac Terminal. We will explore that in more detail in the next section. If you are a little unsure about the concept of a file path, no worries. So, if you would like to learn something about file paths, read on and we will explore this topic. If you are unfamiliar with what a path is, I will also give you a brief overview. Stick with me if you would like to find out more about this topic.
Using Mac Terminal is no different and I can show you how.
#Bash find file path software#
I’m Eric, a software engineer for nearly 25 years, I have used command-line interfaces on many different systems, and finding the path of a file is something I do regularly in my everyday job. There are a few different scenarios in which you may find yourself when trying to determine a file path and in all of them, this can be done rather quickly using the Terminal app. In either case, Mac Terminal is a great method to use when you need to find this information. There are also instances where you need to know the path for an application. Many times those tasks involve the need to know the path of a file. The idea is to familiarize you with a few techniques that could make your work less error-prone and more fun.Mac Terminal is a powerful tool that lets you perform an endless number of tasks from the command line. I am sharing what I know and what I deal with daily. There is certainly more to Bash than I was able to cover in this two-part blog post. There are many other complex actions I can perform on the remote host. One way is to enter: $> ssh remote_host 'bash -s' exec ssh remote_host ARG1=FOO ARG2=BAR 'bash -s' printf %s I can also execute a local script on the remote host without having to copy the script over to the remote server. This command runs ls /etc on the remote host. To see if a remote server is running a web, database, SSH, or any other service, run: $> timeout 3 bash -c ‘ timeout 3 bash -c ‘ ssh remotehost ls /etc These tools are handy, but they aren't installed by default on all systems.įortunately, there is a simple way to test a connection without using external tools. I use Telnet, netcat, Nmap, and other tools to test whether a remote service is up and whether I can connect to it. To delete files older than 30 days, run: $> find /tmp -type f -mtime +30 -exec rm -rf 2> to_stderrĪs you can see, only "Hello world" is printed on the screen, but the output of the failed commands is written to the to_stderr file. To list files older than 30 days, I simply run: $> find /tmp -type f -mtime +30
Let's get more familiar with this command. With find I can list files older or newer than a specific date, delete them based on that date, change permissions of files or directories, and so on. It is extremely useful in interactive shells. The find command is probably one of the most used tools within the Linux operating system. For example, the $PATH shell variable can be expanded by running: $> echo $PATH Use the echo command to expand variables. These are a few frequently-used variables: $PATH Why would I use hostname when I can use $HOSTNAME, or why would I use whoami when I can use $USER? Bash variables are very fast and do not require external applications. The Bash variables are set by the shell when invoked. In this segment, I cover shell variables, find, file descriptors, and remote operations. In part one, I covered history, last argument, working with files and directories, reading files, and Bash functions. This blog post is the second of two covering some practical tips and tricks to get the most out of the Bash shell. How well do you know Linux?
