Top Forums Shell Programming and Scripting Script to find min for each unique value Post 302948768 by ncwxpanther on Thursday 2nd of July 2015 08:39:52 AM
Old 07-02-2015
The above script does not seem to be working for me when used in the following way -

Code:
for year in "${file}"/{1950..2015}01.pnt 
do
cat "$year"
done |
awk '{n=$3; $3=x} !($0 in A) || n<A[$0] {A[$0]=n} END{for(i in A) print i A[i]}' > output.txt

I need it to search through all the January's in years 1950-2015 and grep out the minimum value in Column 3 of each unique value contained in Columns 1 and 2.

Any suggestions?

NAME
script-email - Amanda script to send email notifications DESCRIPTION
script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the addresses specified in the MAILTO property. PROPERTIES
This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API, script configuration. MAILTO List of email addresses that will receive an email on command execution. It is a multi-valued property: property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com" EXAMPLE
In this example, script-email is scheduled to be run before the DLE, on the server. The unqualified email address amanda will be passed to the email system unchanged. The script is then attached to a dumptype, which can then be specified for any DLEs which require notification. define script-tool pre-email { comment "email me before this DLE is backed up" plugin "script-email" execute-on pre-dle-backup execute-where server property "mailto" "amanda" } define dumptype user-tar-email { user-tar script "pre-email" } SEE ALSO
