filename construction and Unix shell command


greetings:

i would like to execute unix shell command from Mma:

(!somecommmand )

as an argument to the command, i would like to construct various

pathnames....

/a/b/c/file1    /a/b/c/file2  ... et. al.

so define:

cdir = "/a/b/c/"

onefile = StringJoin[cdir,"file1"];
twofile = StringJoin[cdir,"file2"];



!somecommand onefile

complaints about the evaluation of the expression onefile:

"/a/b/c/file1"

what the shell command would like is:

!somecommand /a/b/c/file1

so how do we build the pathname and still satisfy the shell command?

thanx

m. r.

ps. i tried all manner of ToCharacterCode, ToExpression, etc., that
i could think of.
