Top Forums Shell Programming and Scripting How to remove contents from file which are under bracket? Post 303003244 by MadeInGermany on Monday 11th of September 2017 04:28:52 AM

Yes, you must find a way to pass the host input into an array, like
Code:
awk -v hosts=host1,host2 'BEGIN {split (hosts,H,",")}'

Then you can cycle through them, as demonstrated here
Code:
for (i in H) print H[i]

The hosts= needs to be passed with -v at the beginning (not at the end as I did with the host=) so it is available in the BEGIN section.
Then in the existing code, where there is a reference to host replace it by a for loop through H.
I leave the actual implementation to you.
For clarity you can always use an explicit { block }, for instance
Code:
  for (i in H) { print H[i] }

or
Code:
  for (i in H) {
     print H[i]
   }

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.
