我要做的就是按输入日期对流程进行排序。这是我保存日期的方式:
#!/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
我现在如何显示流程?谢谢。
您可以使用ps -eo lstart
解析日期,在这里您可以查看特定日期的过程
#!/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"
read val
if [[ $val =~ ^[0-9]{4}-[0-9]{2}-[0-9]{2}$ ]]
then
echo "Date is valid!!"
monthNumber=${val:5:2}
correctDateFormat="${val:0:4}-${MONTHS[$monthNumber]}-${val:8:3}"
ps -eo lstart,pid,cmd | awk {'print $5 "-" $2 "-" $3 " " $6 " " $7'} | grep "$correctDateFormat"
else
echo "Date is not valid"
fi
