I have the following script collecting data about current logged users.
#!/bin/bash # Collecting users login statistics CURRENT_ALL_USERS="path_to_log_file" ADMIN="path_to_admin_dir" STATIONS="$ADMIN/stations_list" ALL_USERS_IN_STATIONS=0 eval `keychain --eval ~/.ssh/id_rsa` for STATION in `cat $STATIONS`; do TEMP_VAR=`ssh user@$STATION who | cut -d " " -f1 | sort -u | wc -l` USERS_IN_STATION=$TEMP_VAR let ALL_USERS_IN_STATIONS="$ALL_USERS_IN_STATIONS+$USERS_IN_STATION" done echo $ALL_USERS_IN_STATIONS > $CURRENT_ALL_USERS
Run periodically with cronjob:
* * * * * /path_to_script/script.sh
When the server reboots the script can't ssh to remote stations and I need to manually run the script for the first time.
What can I do to make the script work after reboot without manually running it the first time?
