Iīm not sure about your question but letīs go: to replace a variableīs value with anotherīs variableīs value, just do this:

e1=$v2;e2=$v3

and so on. Iīm not sure if thatīs your question but if you yant I can send you a documentation about Bash Shel Scripting.

Note: there are some differences between the existing shells (bash, bourne, korn. c-shel, ...)

any comments, be free...

Hi

e1=$v2
but in your script first specify which your shell (korn shell)
#!/bin/ksh
that's it
