LOG ANALYSIS SCRIPTS

>> Check for memory usage
grep "buffers/cache" /var/log/recap/resources_* | sed 's/^.*resources_\(.*\)\.log.*cache:\s*\([0-9]*\)\s*\([0-9]*\)$/FREE: \3| USED: \2| DATE: \1/ '

>> Running the following to check if the memory went less than 4999MB
grep "buffers/cache" /var/log/recap/resources_* | sed 's/^.*resources_\(.*\)\.log.*cache:\s*\([0-9]*\)\s*\([0-9]*\)$/FREE: \3| USED: \2| DATE: \1/ ' | egrep -v "FREE: [65][0-9]{3}\|" | wc -l

 

Find files based on date/time 

# ONE LINERS


> Modified in the last 12 hours (720 min)
find . -cmin -720 

> Modified in the last day
find . -mtime -1



# => ctime - for hacked/modified files 
# look for ctime instead, hacked scripts can't set that to what they want as opposed to mtime:

find -cmin -$n_minutes_ago
find -ctime -$n_days_ago
ls -lc   ## sorted by name
ls -ltc   ## sorted by time


>> File OLDER THAN xx days:
find . -type f -ctime +$n_days_ago

>> Find files RESTORED older that xx days and MOVE them
find . -type f -mtime +$n_days_ago | xargs -I '{}' mv {} /destination/path/
