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.
This is what I have so far:
Code:
cd $dir_old
for name in MC*
do
if [test -e $dir_new$name.CP]; then
diff -s "$name" "$dir_new$name.CP" >> logfile
fi
done
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 very new to C and could use a little help.

fprintf(stdout, "name = %s length = %d\n",argv,l);
usage(0);
}
This works if the command is... (3 Replies)

diff
DIFF(1) General Commands Manual DIFF(1)NAME
diff - print differences between two files
SYNOPSIS
diff [-c | -e | -C n] [-br]file1 file2
OPTIONS -C n Produce output that contains n lines of context
-b Ignore white space when comparing
-c Produce output that contains three lines of context
-e Produce an ed-script to convert file1 into file2
-r Apply diff recursively to files and directories of
EXAMPLES
diff file1 file2 # Print differences between 2 files
diff -C 0 file1 file2
# Same as above
diff -C 3 file1 file2
# Output three lines of context with every
diff -c file1 file2 # Same
diff /etc /dev # Compares recursively the directories /etc and /dev
diff passwd /etc # Compares ./passwd to /etc/passwd
DESCRIPTION
the same name, when file1 and file2 are both directories" difference encountered"
Diff compares two files and generates a list of lines telling how the two files differ. Lines may not be longer than 128 characters. If
the two arguments on the command line are both directories, diff recursively steps through all subdirectories comparing files of the same
name. If a file name is found only in one directory, a diagnostic message is written to stdout. A file that is of either block special,
character special or FIFO special type, cannot be compared to any other file. On the other hand, if there is one directory and one file
given on the command line, diff tries to compare the file with the same name as file in the directory directory.
