I'm new to shell scripting, and I need to do a diff between two dirs. One of them (dir_old) contains many files, and the other (dir_new) contains just a set of 8 files, all starting with MC and extension .CP.
The problem I have is that dir_old contains about 20 files that start with MC and with no extension, so I need to check if the files in dir_new exist before using the diff.
Assume $x equals "".
If I try:
if test -n $x
I get the "Expression syntax" error.
It works in Linux but not in unix bash. In unix bourne I get "test: argument expected" (4 Replies)

I'm testing to make sure the command is running as it's proper name, if not then fail.

fprintf(stdout, "name = %s length = %d\n",argv,l);

gendiff
GENDIFF(1) General Commands Manual GENDIFF(1)NAME
gendiff - utility to aid in error-free diff file generation
SYNOPSIS
gendiff <directory> <diff-extension>
DESCRIPTION
gendiff is a rather simple script which aids in generating a diff file from a single directory. It takes a directory name and a "diff-
extension" as its only arguments. The diff extension should be a unique sequence of characters added to the end of all original, unmodi-
fied files. The output of the program is a diff file which may be applied with the patch program to recreate the changes.
The usual sequence of events for creating a diff is to create two identical directories, make changes in one directory, and then use the
diff utility to create a list of differences between the two. Using gendiff eliminates the need for the extra, original and unmodified
directory copy. Instead, only the individual files that are modified need to be saved.
Before editing a file, copy the file, appending the extension you have chosen to the filename. I.e. if you were going to edit somefile.cpp
and have chosen the extension "fix", copy it to somefile.cpp.fix before editing it. Then edit the first copy (somefile.cpp).
After editing all the files you need to edit in this fashion, enter the directory one level above where your source code resides, and then
type
$ gendiff somedirectory .fix > mydiff-fix.patch
You should redirect the output to a file (as illustrated) unless you want to see the results on stdout.
