the simplest way to tackle this problem is at the source, by not using "/" as the field separator.

Hello!
I know that this expression gets rid of non-alphanumeric characters:
sed 's///g'
and I understand that it is replacing them with nothing - hence the '//'-, but I don't understand how it's doing it.
It seems it's finding strings that begin with alphanumeric and replacing them with... (2 Replies)

hotswaprc
HOTSWAPRC(5) File Formats Manual HOTSWAPRC(5)
NAME
hotswaprc - configuration file for hotswap
DESCRIPTION
/etc/hotswaprc is the global configuration file for the hotswap utility.
It allows system administrators to specify arbitrary shell scripts to be run after a device is inserted, as well as before and after it is
removed. Scripts are selected according to the model name retrieved from the device. This is particularly helpful for automatic configura-
tion of CD-RW drives, which require SCSI emulation and bypass normal access via the IDE subsystem.
hotswaprc is implemented as an Extensible Mark-up Language (XML) application. XML documents are structured using elements of the form
<tag-name> content <tag-name>. A Document Type Definition (DTD) describes the possible content of each element.
Please refer to the XML specification for more information. The hotswap distribution also contains an example file, doc/hotswaprc.example,
which includes the DTD for the configuration file format.
ELEMENTS
<hotswap>
This is the root element of the document. Each valid hotswaprc must contain exactly one <hotswap> element. The <hotswap> element may
contain an arbitrary number of <device> elements.
<device>
The configuration file contains one <device> element for every device for which scripts are defined. The <device> element is com-
posed of the following elements in this order: <name>, <post-insert>, <pre-remove>, <post-remove>. All but <name> are optional.
<name> The content of this element is the model identification string of the IDE device the current <device> element refers to.
<post-insert>
Contains the shell script that is to be executed after the device has been inserted and registered with the kernel.
<pre-remove>
Contains the shell script that is to be run before hotswap attempts to unregister the device.
<post-remove>
Contains the shell script that is to be run after the device had been unregistered.
