# This script trims the fsq_audit_log.txt file
|
|
# in the ~/.fldigi/temp folder by removing content added aded earlier
|
|
# than the supplied time (e.g. "10 days ago" or "1 hour ago").
|
|
#
|
|
# Parameter 1 is a date reference e.g. "10 days ago" or "1 hour ago"
|
|
#
|
|
# This script will not run if Fldigi is running. It must be run
|
|
# prior to starting Fldigi. If you want to run it every time you start
|
|
# Fldigi on a Raspberry Pi, change the File Properties
|
|
# of the Fldigi menu item to run this script and then Fldigi as follows:
|
|
#
|
|
# Click on the Raspberry and navigate to the menu containing Fldigi. Right-click
|
|
# on the Fldigi menu item, click Properties then select the "Desktop Entry" tab.
|
|
# In the Command field, replace 'fldigi' with the following (change the
|
|
# time period as desired):
|
|
#
|
|
# sh -c '/usr/local/bin/trim-fsq-audit.sh "30 days ago"';fldigi ...
|
|
#
|
|
# Leave the "Execute in terminal" box unchecked, then click OK.
|
|
#
|
|
# If you want to run both this script and the trim-fsq-heard.sh script in the
|
|
# same way, use this line in the Command field instead (change the time period
|
|
# as desired):
|
|
#
|
|
# sh -c '/usr/local/bin/trim-fsq-audit.sh "30 days ago";/usr/local/bin/trim-fsq-heard.sh "1 hour ago"';fldigi
|
|
#
|
|
|
|
# Exit if Fldigi is already running
