You need to retrieve the current value - add then set the value with the old value + your new value

Rishi,

Not seen your code... but its simple... just use -g to extract the value of the attibute. If it is defined value just cancatenate along with new value and set the same using -s. If -g gives u undefined then also set the attribute vaue using -s.

Just try the same.. and revert if you still have any problem.

The code you show gets all the EAs on the file - I don't see anyplace where you're trying to reset a specific EA entry - so I have nothing to base any code suggestions on.

But in short - you can either use something like:

chomp(my $val = qx($iwhome/bin/iwextattr -g "$eaname" "$fname"));
$val .= ";$newval";
chomp(my $results = qx($iwhome/bin/iwextattr -s "$eaname=$val" "$fname"));

or you can use the '-x' flag and pull the EAs into XML format - and then add the new value that way.

I think you're asking how to set more than one value. You do that by providing a coma separated list

EG

iwextattr -s "some_tag=val1,val2,val3"

Just a guess at what your specific issue is.

Thanks john, but my req is to just add the metadata with the existing one so it will looks like :

TeamSite/Metadata/microsite: 5
TeamSite/Metadata/microsite: 1
TeamSite/Metadata/microsite: 33

thanks ghoti, i will try to do that way....

Thanks john, but my req is to just add the metadata with the existing one so it will looks like :

TeamSite/Metadata/microsite: 5
TeamSite/Metadata/microsite: 1
TeamSite/Metadata/microsite: 33

Then you have a requirement you can't meet. You can not have more than one extended attribute with the same name. You will either need to use a delimiter, as everyone else has said, or different variable names. For example:

TeamSite/Metadata/microsite1: 5
TeamSite/Metadata/microsite2: 1
TeamSite/Metadata/microsite3: 33

FYI - I believe the default is semi-colon separated list, not comma-separated (though I could be wrong about this)

The script you posted is only meant to print out the extended attributes for files. It says exactly this in the description. Do you have any idea what the script is even doing? As several people have already said, if you want to get EAs, use iwextattr -l and store the results in a hash. If you want to set EAs, use iwextattr -s. And you can not have more than one EA with the same name, as everyone has already pointed out to you.

this is the initial script and i use -l for testing purpose. my req is i have 2 drop down select list (source and destination) in my workflow. so if user select any opt from source select list, the same EA needs to be set on second select list value.

Ok, so you have two selects. You get the value from select 1 and 2 and store them in $selectOneValue and $selectTwoValue. You then set your eas:
`iwextattr -s "selectOneValueEA"="$selectOneValue" $dcrPath`;
`iwextattr -s "selectTwoValueEA"="$selectOneValue;$selectTwoValue" $dcrPath`;Make the needed modifications to make it work in your script and you're good to go.

~Jeff

can you just correct me to get the first value of the following. in your reply

`iwextattr -s "selectOneValueEA"="$selectOneValue" $dcrPath`;

or

`iwextattr -g "selectOneValueEA"="$selectOneValue" $dcrPath`;

My example was setting, not getting. I would assume the values you are getting are not EAs yet, but coming from post data. If they are already EAs, why would you need to get them and set them again?
