# startup.sh(8)

default startup script of ledd(8)

## NAME

startup.sh - default startup script of [**ledd**(8)](/ledd/8.md)

## DESCRIPTION

**startup.sh** is part of the ledcontrol package, which allows you to show arbitrary information on the normally-unused keyboard LEDs. **startup.sh** is the default startup script that [**ledd**(8)](/ledd/8.md) uses. It is configured in */etc/ledcontrol.conf* and checks the given conditions every few seconds (by default every 5 seconds).

**startup.sh should not be executed by the user,** instead, it is started by [**ledd**(8)](/ledd/8.md) on startup. See [**ledcontrol.conf**(5)](/ledcontrol.conf/5.md) for details on configuring **startup.sh**.

## SILENCING

**startup.sh** may cause a disk-access every time it check the conditions. This is due to the access-time feature of the ext2 filesystem. If this bothers you, you can disable the access-time updating from some files.

**Do NOT try this unless you know what you are doing!**

Mounting a partition with the option "noatime" disables the access-time updates of the files on that filesystem. You can add this option in */etc/fstab* to have the filesystems mounted with it by default. You probably need to have it set for some files in */usr* and maybe */lib*. If you do not want to remove the access-time feature of all the files, you may be able to create a small partition (or file) containing the necessary libraries and programs and using that.

Another option is to use [**chattr**(1)](/chattr/1.md) to remove the access-time updating of only certain files. I have not tried this, so if you do, please tell be how it works out.

## BUGS

**bash** version 2.xx.xx has a bug in it that causes *startup.sh* to lock up if backgrounding is used. From version 0.5.0 up this has been checked by *startup.sh* and if a bad version of **bash** is being used the option **USE\_BACKGROUNDING** is automatically set to "NO" (see [**ledcontrol.conf**(5)](/ledcontrol.conf/5.md)).
