== Important facts about 7-zip
|
||||
* 7-zip does NOT store the owner/group of the files/folders being archived, which is good for privacy, but may not suite your specifc use case, especially as a back up tool.
|
||||
* 7-zip is a name of the compression tool created by Igor Pavlov.
|
||||
* While Igor Pavlov provides Linux/macOS versions as well, another implementation by independent developer (Mohammed Adnene Trojette) has become wide used in the Linux realm - `p7zip`. This cookbook relates to this, independent version, so options and switches may differ a bit from 7-zip Windows canonical version.
|
||||
|
||||
== Install p7zip package on Linux
|
||||
This tool is already in all the major repositories, so you should have no problems installing it.
|
||||
|
||||
`Ubuntu`: `sudo apt install p7zip-full`
|
||||
|
||||
`CentOS/Fedora`: `sudo yum install p7zip p7zip-plugins`
|
||||
|
||||
== Create an archive adding all the files in the current folder
|
||||
We first indicate to `7-zip` that we want to _add_ to an archive with `a` command, then we specify the archive name, and finally, we use `*` as wildcard to include all files in the current folder.
|
||||
|
||||
`7z a folder.7z *`
|
||||
|
||||
The result - _folder.7z_ will be placed in the same folder where it run.

|

|Command
|
||||
|Description
|
||||
|
||||
|*rem*
|
||||
|Start a comment, till the end of line. It can be used to comment out a whole line or part of it.
|
||||
|
||||
|*cls*
|
||||
|Clear the screen buffer.
|
||||
|
||||
|*echo _text to display_*
|
||||
|
||||
*echo off/on*
|
||||
|
||||
*echo.*
|
||||
|Print text on line, or, with `off/on` switch without text, turn off/on echoing the commands being run.
|
||||
Usually, you set `echo off` as the 1st line in a batch script, and the `echo on` as the last line. Turning
|
||||
echoing off does not hide _output_ of the commands run, just the commands themselves. The 3rd option is `echo` followed immediately
|
||||
by _dot_ and it causes echo to print a blank line (an dthis is the only way to do so).
|
||||
|
||||
|*@*
|
||||
|Turn off echoing only for the command preceded by this @. E.g. `@echo off` to prevent the _echo off_
|
||||
being printed itself.
|
||||
|
||||
|*title _Title bar text_*
|
||||
|Change the title of the cmd.exe window for this session. As a rule of a good style, change _title_ on each stage of the
|
||||
script, to let users know what the script is doing.

|

|Command
|
||||
|Description
|
||||
|
||||
|%_n_
|
||||
|Positional argument to the script from the command line. _n_ can be from 0 to 9.
|
||||
|
||||
|%0
|
||||
|The script name. The actual arguments to the script start with %1.
|
||||
E.g. `echo The script was called as %0, with the %1 as the first argument`
|
||||
|
||||
|%*
|
||||
|The rest of the positional arguments after the 9th altogether. The individual args are not accessible directly, use `SHIFT`-ing.
|
||||
|
||||
|*shift [/_n_]*
|
||||
|Shift positional arguments by one. If `/n` is given, will shift starting with n+1. E.g. `shift /4` will shift 5th to become 4th,
|
||||
6th will become 5th, and so on, while arguments before 4 will stay untouched.
