Solved How To Find Character Position In String Using Unix.

One way is to use the set command to parse the string where each segment is set to one of the command line variables and the total number of variables is $#

Warning: I haven’t tested it, but you might have a problem if you have 10 or greater variables.

Let me know if you have any questions:

#!/bin/ksh

str="abc_def_ghg_hij"
set $(IFS="_"; echo $str)
###echo $# # number of variables should be 4
nv=$#

# create var1 to var4
i=1
while (($i <= $nv))
do
   eval var$i=\$$i
   ((i+=1))
done
#echo $var1

# display variables var1 to var4
h=1
while (($h <= $nv))
do
   eval echo "\$var$h"
   ((h+=1))
done
