All I'm trying to do is to sort the processes by an input date. This is how I saved the date:
#!/bin/bash
echo "Insert the date yyyy-mm-dd"
read a
if ! [[ $date =~ ^[0-9]{4}-[0-9]{2}-[0-9]{2}$ ]]
then echo "Date is not valid"
elif b=`date --date=$a '+%Y-%m-%d'`
then
????
fi
How can I show the processes at this date? Thanks.
You can specify a formatter and use lstart, like this command:
ps -eo lstart,pid,cmd
The above command will output all processes, with formatters to get date+time, PID started, and command run, but i have changed the date format to be align with your date input
This is what you looking for :
#!/bin/bash
declare -A MONTHS
#months Dictionary
MONTHS[01]=Jan
MONTHS[02]=Feb
MONTHS[03]=Mar
MONTHS[04]=Apr
MONTHS[05]=May
MONTHS[06]=Jun
MONTHS[07]=Jul
MONTHS[08]=Aug
MONTHS[09]=Sep
MONTHS[10]=Oct
MONTHS[11]=Nov
MONTHS[12]=Dec
echo "Insert the date yyyy-mm-dd"
IFS="-" read -a val
if [[ "${val[0]}-${val[1]}-${val[2]}" =~ ^[0-9]{4}-[0-9]{2}-[0-9]{2}$ ]]
then
echo "Date is valid!!"
ps -eo lstart,pid,cmd --sort=start_time | \
awk {'print $5 "-" $2 "-" $3 " " $6 " " $7'} | \
grep "${val[0]}-${MONTHS[${val[1]}]}-${val[2]}"
else
echo "Date is not valid"
fi
