Script to download extensions+dependencies on other Linux distros

General TC > Programming & Scripting - Unofficial

<< < (4/9) > >>

xor:
I'm asking to understand the working logic!?

How do we call 32-bit dependencies on 64.bit!?

Juanito:
Everything is explained in the first post of this thread.

Rich:
I've attached an updated copy of FetchExt.sh to this post.

You can now enter multiple extensions in one command and it no longer matters whether or not you include
.tcz in the extension name:

--- Code: ---tc@E310:~/Scripting/FetchExtensions/tmp/debug$ ./FetchExt.sh 9vx xt_geoip_LE_IPv4 9vx.tcz xyzzy 915resolution.tcz xyzzy.tcz
..........
tc@E310:~/Scripting/FetchExtensions/tmp/debug$
--- End code ---
I replaced excess screen output with dots to indicate progress since the Log.txt file has a record of all activity anyway.

This is the log file from the above command:

The lines that begin with Processing refer to the extensions from the command line. That's what you add to
your onboot.lst file,
The lines after that give the results for that extension and all dependencies.
Errors are indented for better visibility.

I've also attached a ShowErrors.sh script. It parses the Log.txt script created by FetchExt.sh and outputs a
formatted list of any errors found:

--- Code: ---tc@E310:~/Scripting/FetchExtensions/tmp/debug$ ./ShowErrors.sh

tc@E310:~/Scripting/FetchExtensions/tmp/debug$
--- End code ---
The xtables-addons error shows that the 64 bit module extension is missing from the TC10 x86 repository.
The Error: Processing message means the extension you requested from the command line does not exist.

The script now creates a list of kernel versions in the repo. If a kernel extension is needed, the script attempts to
download all kernel versions of that extension. Since the OS will load the correct version, it's just simpler that way.
PiCore sometimes has multiple versions. X86 supports core and core64, so we download both versions.

Remember to make the script make it executable:

--- Code: ---sudo chmod 777 FetchExt.sh
--- End code ---

Remember to edit the version and architecture variables to match your system:

--- Code: ---# User variables ***************************************************************

# Website to download from.
ADDR="http://repo.tinycorelinux.net"

# Tinycore version. Versions always end in .x , there are no minor version digits.
TC="10.x"

# Processor architecture, current options are x86 x86_64 armv6 armv7 armv7l aarch64
ARCH="x86"

# End of user variables ********************************************************
--- End code ---

I think the script is fairly well documented if you want to see what's going on. Comments and criticism are welcome.

[EDIT]: Attachments removed. A link to the current version is in the first post of this thread. Rich

GNUser:
This is great, Rich. Thank you.

Just two comments:

1. == is a bashism, which leads to "unexpected operator" errors with the /bin/sh shebang (see https://mywiki.wooledge.org/Bashism). Changing every [ "foo" == "bar" ] in the script to [ "foo" = "bar" ] solves the problem.

2. The three chown steps require superuser privileges. It seems the two options are either to run the entire script as superuser or to change the three chown commands to sudo chown . I prefer doing as little as possible as superuser, so I went with the second option. The downside to my approach is that it is slightly less portable since not every user on every OS has sudo installed.

I will keep the script handy. I was using the old version to help me upgrade from one TCL version to the next, but this new version is even better :)

doctoranonymous reported the same issue in reply #8. I was not able to reproduce the issue (reply #11)
http://forum.tinycorelinux.net/index.php/topic,23034.msg146361.html#msg146361
I did a little searching and I think the correct syntaxes are:
[ "$1" = "info" ] for strings.
[ $? -eq 0 ] for integers (equal).
[ $? -ne 0 ] for integers (not equal).

Could I ask you to change the tests of $? to the appropriate integer tests and see if that also fixes the error?
