Hello,
Looks like pattern parameter expansions:
${parameter#word}, ${parameter##word},
${parameter%word}, ${parameter%%word},
${parameter/pattern/string} and ${parameter//pattern/string}),
parameter length expansion ${#parameter},
error expansions:
${parameter:?error message} and ${parameter?error message}
varnames expansion:
${!prefix*} and [EMAIL PROTECTED]
are bashisms too and checkbashisms doesn't check for these.
For example, on Solaris the above expansions doesn't work
(${parameter:-word}, ${parameter:=word} etc. do):
> [EMAIL PROTECTED]:~$ cat subst.sh
> #!/bin/sh
> (echo '${PATH} =' ${PATH})
> (echo '${PATH+/bin} =' ${PATH+/bin})
> (echo '${PATH:+/bin} =' ${PATH:+/bin})
> (echo '${PATH-/bin} =' ${PATH-/bin})
> (echo '${PATH:-/bin} =' ${PATH:-/bin})
> (echo '${PATH=/bin} =' ${PATH=/bin})
> (echo '${PATH:=/bin} =' ${PATH:=/bin})
> (echo '${PATH?No PATH} =' ${PATH?No PATH})

checkbashism knows only about substring expansion and
replace expansion though:

> (echo '${PATH/local/loc} =' ${PATH/local/loc})
> possible bashism in ./subst.sh line 21 (${parm/?/pat[/str]}):
> (echo '${PATH//local/loc} =' ${PATH//local/loc})
