running a simple script file with multiple commands
I'm trying to run a script file with multiple commands that I would normally type into the command line. The commands are:

#!/bin/bash
diff Test1.o0 /usr3/ronelso4/Desktop/verificationKPC/Test1.o0 > differences2
diff Test1a.o0 /usr3/ronelso4/Desktop/verificationKPC/Test1a.o0 >> differences2
diff Test2.o0 /usr3/ronelso4/Desktop/verificationKPC/Test2.o0 >> differences2
diff Test2a.o0 /usr3/ronelso4/Desktop/verificationKPC/Test2a.o0 >> differences2

For some reason when I execute it all I get in the file are the last files differences not all of the files. What am I doing wrong?

Hope I'm not starting with the too-obvious, but are you sure that there actually *are* any differences in the first 3 diffs? And you're sure that the diffs that are in the file are from the last diff? You could output each diff to a different file, instead of to the same file, and see what happens. Other than that, nothing looks incorrect in what you're doing. You might try:
Code:
#!/bin/bash
diff Test1.o0 /usr3/ronelso4/Desktop/verificationKPC/Test1.o0 > differences1
diff Test1a.o0 /usr3/ronelso4/Desktop/verificationKPC/Test1a.o0 > differences1a
diff Test2.o0 /usr3/ronelso4/Desktop/verificationKPC/Test2.o0 > differences2
diff Test2a.o0 /usr3/ronelso4/Desktop/verificationKPC/Test2a.o0 > differences2a
cat differences1 differences1a differences2 differences2a >> differences.all

In theory. that *should* give exactly the same end result (except for the filename) as your setup. Does it?
