converting ksh to bash - typeset commands

view story

http://www.unix.com – Hi all, Am trying to convert a script written in ksh to a bash shell. At the moment, am stumped with the typeset -u command and I can't find an equivalent of it in bash. integer function is also not working as is the following if statement Code: if [[ $inst = @(dev01|dev02) ]] && [[ `hostname` = wlgprod001 ]]; then   continue fi Is there any site out there that discusses about converting ksh to bash and the gotchas? Please advise how to get around this? (HowTos)
