How to parse a string into variables
I'm working in korn shell and have a variable which contains a string like:
aa_yyyymmdd_bbb_ccc_ddd.abc. I want to treat the _ and . as delimiters and parse the string so I end up with 6 values in variables that I can manipulate. My original plan was to use var1=`echo $sting1 | cut -c1-c2` but now the requirements have changed so the position is no longer fixed. Please help.

Code:
$ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" aa_yyyymmdd_bbb_ccc_ddd.abc $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" aa_yyyymmdd_bbb_ccc_ddd.abc $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" | cut -d"." -f 2 abc $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" | cut -d"_" -f 1 aa $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" | cut -d"_" -f 2 yyyymmdd $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" | cut -d"_" -f 3 bbb $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" | cut -d"_" -f 4 ccc $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" | cut -d"_" -f 5 ddd.abc $ echo "aa_yyyymmdd_bbb_ccc_ddd.abc" | cut -d"_" -f 5 | cut -d"." -f 1 ddd
