The benefit, a smaller file size means faster uploading for you and faster downloading for your friend. You want to decrease the file size and also chop it up into several pieces before you start uploading. Scenario 2: You have a large file that you want to upload and share with a friend. Compressing the files may make them small enough to fall under the size limit. Sometimes the amount and size of the files you want to send via email exceeds the limit.
The benefit, the email uploads faster and your friend is able to download the email faster reducing the waiting time both ways.
You compress the files making them smaller in size. Scenario 1: You want to send some files via email to a friend. Why would you want to create a compressed file you may ask? I could think of several reasons I have created compressed files, here are a few of them… Compressing a file or group of files shrinks up the file sizes, sometimes significantly. Z.īesides opening up files 7-zip can also create compressed files. 7-zip can open (“unzip”) the following file formats…ħz. The program is compatible with all versions of Windows, Mac and Linux. I will show you how to open or as the computer nerds say, “decompress” the most popular file compression formats using the free application named, “7-zip”.ħ-zip is a free file archiver software program. It didn’t matter if you knew it was a compressed file format or not, you did not know how to open it. It had a weird file extension that you did not recognize. (Also, TIL people use new reddit, and it supports three backticks.I am sure many of you have downloaded a file and could not read it. Printf - '%s\n' "$" >&2ĮDIT: fixed missing shebang. There's probably a couple of things I could do to square this off a bit. I was working on making the tar handling a bit more robust, but it dawned on me that to do that robustly would be a lot of work, so I stopped further work. Here's an untested rewrite of my own variant of this that I dug up, feel free to copy anything you find useful. edit: I previously had a link to an older version of this.
Please indent by four spaces instead, your post will then be accessible to a wider audience. *) echo "'$1' cannot be packed via pk()" įYI: Your code is an unreadable mess on oldreddit where triple backtick syntax doesn't work. They're quite simple, here's extract: #!/bin/shĮcho "Extract a given file based on the extension."Įcho "Error: '$1' is not a valid file for extraction" I've used similar (simplier though) thing for years, but for me it's just 2 scripts: extract and pk.
