[SOLVED] Split a string having multiple delimeters using shell script

Issue

```

I have a string in the below format aYbMTcDdHeMfs where a,b,c,d,e and f are numerics of any length. Y-> Years MT-> Months D-> days H-> hours M-> minutes S-> Seconds

```

The string can have anything like

1H2M3S
1Y2MT3D4H5H6S
1Y20S 
.. so on.


Here the input has the same order of years,months,days,hours,minutes and seconds.

    If we want to fetch the value of years, months, days, hours, minutes, and seconds from the string then what would be the shell script to convert it into seconds?
    
    1H20S -> 3620
    
    10M200S -> 800
    
    10M100S -> 700

Can you help me with the script to find those?

Solution

Your specification is incomplete but here's a couple of ideas to get you started:

#!/bin/bash
    
aYbMTcDdHeMfS(){
    x=${1//Y/*31536000+}
    x=${x//MT/*2628000+}
    x=${x//D/*86400+}
    x=${x//H/*3600+}
    x=${x//M/*60+}
    x=${x//S/+}
    x=${x%+}
    echo "$((x))"
}

aYbMTcDdHeMfS            1H  # 3600
aYbMTcDdHeMfS         15S3M  # 195
aYbMTcDdHeMfS        1H2M3S  # 3723
aYbMTcDdHeMfS 1Y2MT3D4H5H6S  # 37083606
aYbMTcDdHeMfS         1Y20S  # 31536020
aYbMTcDdHeMfS         1H20S  # 3620
aYbMTcDdHeMfS       10M200S  # 800
aYbMTcDdHeMfS       10M100S  # 700
