Top Forums Shell Programming and Scripting ksh: A part of variable A's name is inside of variable B, how to update A? Post 67835 by vgersh99 on Monday 28th of March 2005 03:57:46 PM
Old 03-28-2005
here's something to start with as I'm still a bit confused....

Code:
#!/bin/ksh

typeset num;

for iter in 1 2 3 4 5 6 7 15 123
do
   varb="test$(printf "%02d" ${iter})"
   vara="${varb}_count"
   # increment vara
   #
   num=$(printf "%02d" $(( $(echo "${vara}" | sed -e 's/^[^0-9]*\([0-9][0-9]*\)_.*/\1/') + 1 )) )
   echo "varb->[${varb}] vara->[${vara}] incrementedNum->[${num}] incrementedVarA->[test${num}_count]"
done;

       The command `tcbtest' is a utility for facility test and performance test.  This command is used in the following format.  `path' specifies
       the path of a database file.  `rnum' specifies the number of iterations.  `lmemb' specifies the	number	of  members  in  each  leaf  page.
       `nmemb'	specifies the number of members in each non-leaf page.	`bnum' specifies the number of buckets.  `apow' specifies the power of the
       alignment.  `fpow' specifies the power of the free block pool.

	      tcbtest write [-mt] [-cd|-ci|-cj] [-tl] [-td|-tb|-tt|-tx] [-lc num] [-nc num] [-xm num] [-df num]  [-ls  num]  [-ca  num]  [-nl|-nb]
	      [-rnd] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Store records with keys of 8 bytes.  They change as `00000001', `00000002'...
	      tcbtest read [-mt] [-cd|-ci|-cj] [-lc num] [-nc num] [-xm num] [-df num] [-nl|-nb] [-wb] [-rnd] path

	      num] [-dai|-dad|-rl|-ru] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Store records with partway duplicated keys using concatenate mode.
	      tcbtest queue [-mt] [-cd|-ci|-cj] [-tl] [-td|-tb|-tt|-tx] [-lc num] [-nc num] [-xm num] [-df num] [-ls num] [-ca num] [-nl|-nb] path
	      rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Perform queueing and dequeueing.
	      tcbtest misc [-mt] [-tl] [-td|-tb|-tt|-tx] [-nl|-nb] path rnum
		     Perform miscellaneous test of various operations.
	      tcbtest wicked [-mt] [-tl] [-td|-tb|-tt|-tx] [-nl|-nb] path rnum
