Check These Out
This command copies all filenames in the current dir and subdirs that end in .mp3 regardless of case (also matches .MP3 .mP3 and .Mp3)
It copies all the files to the "mp3" folder in your home directory.
If you want to see the files that are beeing copied, replace "cp {}" with "cp -v {}"
Some times you may ban usb to protect thefting of your personal data.
Blacklist the usb_storage module by adding blacklist usb_storage to /etc/modprobe.d/blacklist.conf.
To load the module manually,
$sudo modprobe usb_storage.
Far from my favorite, but works in sh and with an old sed that doesn't support '-E'
I learned a few things reading this command. But I did run into a few issues:
1. On systems that don't use GNU echo (e.g. macOS 10.14.5 Mojave), the e option may not be supported. In this case ANSI escape codes will echoed as text and the terminal will not flash, like this:
\e[?5h\e[38;5;1m A L E R T Thu Jun 20 16:31:29 PDT 2019
2. Since the read command strips\ignores leading backslashes, if a user types the backslash character once in the loop, it will not break. Typing backslash twice in a loop will break as expected.
3. The foreground color is set to red (\e[38;5;1m) on every loop. This could be set once before we call while, and then reset once when the loop breaks.
4. Instead of resetting the foreground color when it breaks, the video mode is set back to normal (\e[?5l). This has the effect of leaving the terminal text red until it is manually reset.
The alternative I'm proposing here addresses these issues. I tested it on macOS and Arch Linux.
Shows all configurations to apt and dpkg, rarely changed, you probably still have the default configuration. Go ahead and explore your configuration if you dare, perhaps change your apt-cache directory, Dir::Cache "var/cache/apt/"; or the names of the log files.
Useful when you forget to use sudo for a command. "!!" grabs the last run command.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
