I'm a C shell user.
I've two files.
file 1:
A
B
C
D
Efile 2:
A
C
B
D
EI want to compare only A-A, B-C, C-B, D-D, E-E using a for loop.
If the strings match, then print "match".
The output would look like:
A A -> match
B C -> " "
C-B -> " "
D-D -> match
E-E -> matchHow do I use the for loop?
Here's a sample script that makes use of the command paste to collate the 2 files into a single list:
A-A
B-C
...
It then parses each combined string into it's 2 descrete parts, and stores them in variables f1 and f2.
#!/bin/csh
foreach i (`paste -d"-" file1 file2`)
set f1=`echo $i | cut -d"-" -f1`
set f2=`echo $i | cut -d"-" -f2`
if ($f1 == $f2) then
echo "$f1 $f2 -> match"
else
echo "$f1 $f2 -> "'" "'
endif
end
The rest of the code is standard C shell.
$ ./cmd.csh
A A -> match
B C -> " "
C B -> " "
D D -> match
E E -> match
