Linux update Oxide automatically sh script

Few days ago I just search for a linux script which can automatically update oxide if an update is released .
Since not found any resource I decide to create one and share it with the community .

This script was build using LGSM scripts and will check for oxide updates based on cURL header hash value and perform following actions (if no oxide updates are detected the script will exit without taking any actions):

• stop rust server
• update rust server (if available)
• update oxide mod for rust
• start rust server

The script can be found attached to this topic and on GIT

You will have only to change WDIR var according to location of LGSM rustserver script .
I have crontabed this script to run hourly at 2 and 32 minutes (in order to avoid interaction with /srv/rust/rustserver monitor)

ChangeLog

- updated to version 0.2
- change detection of new version from sha1 header to etag since bintray seems to use akamai and no more sha1 info can be found in header .
- git version also updated

 

1) Need sudo or root for install, realy?
2) after install php and install ocomposer, errors and errors and errors... May be I need to use it as sudoer or root too? No, thanks

 

ocomposer is not needed by this script , also no sudo or root is required , my rust server uses a dedicate "rust" user under which this script runs .

 

Ye, now I understand. Thanks, will try. Made script, change path to WDIR, but:

Code:

rustserver@gameserver:~/scripts$ ./checkupd_rust
./checkupd_rust: 13: ./checkupd_rust: function: not found
Local Oxide eTAG :
./checkupd_rust: 19: ./checkupd_rust: function: not found
Remote Oxide eTAG : "3141971a4aed147dcd635e583f0b3803:1500848419.253408"
./checkupd_rust: 25: ./checkupd_rust: function: not found
./checkupd_rust: 27: ./checkupd_rust: oxide_get_local_hash: not found
./checkupd_rust: 28: ./checkupd_rust: oxide_get_remote_hash: not found
./checkupd_rust: 29: test: ==: unexpected operator

 

I am not sure what shell he is using but I had to make a couple of changes for bash on CentOS 7. Specifically, function was removed in favor of functionname (). Also changed how the comparision is done (f [ "${LHASH}" = "${RHASH}" ]; then). Otherwise, thanks because I was looking for the right way to do this:
