I am trying to compare two text files and output the difference to another file.
I'm not strictly looking for differences in text but additional text at the end of one file that isn't in another, so basically comparing the file 2 against file 1 and printing any additional text to file 3.
Code
the following is an error output when I run the script:
Error code:
> /usr/asm/atl.1001/user_data/error_logs/LOG1001.TXT^J^J^J: cannot open
Any help greatly appreciated!
It appears that you do not have permission to create /usr/asm/atl.1001/user_data/error_logs/LOG1001.TXT if it doesn't already exist, or you do not have permission to erase the current contents and write new data to that file if it does already exist. What is the output of the command:
after you get that error message?
Just out of curiosity, why do you want to remove the first character of the system's node name when creating a log file for that system?
I have to compare two files for any differences, then output the lab and question number for any differences. This is what I currently have:
diff lab2.txt lab2answer.txt > lab2compare.txt
Though the output doesn't have to be sent to a .txt (or any sort of log), I found that easier, at least... (2 Replies)
I have two files like this:

ABCD 4321 26485
JMTJ 5311 97248
XMPJ 4321 68978
What to do: Compare the two files and find those lines that doesn't match. And have a new file like this:
#FILE 3
"from file 1"

Hi there,
I'm sure this question has been asked many times but I can't find any posts with information.
How can I check the differences between say lines 20 - 200 in file1 and lines 420 - 600 in file2?
Thanks in advance for any help!

I know the diff does this but it does output more info than just the different text
(e.g.
$ diff file1 file2
29a30
> /home/alex/Pictures/hello.jpg
1694a1696
> /home/alex/Pictures/hi.jpg
)
How can I make it output only
/home/alex/Pictures/hello.jpg
/home/alex/Pictures/hi.jpg
?

SGMLDIFF(1)SGMLDIFF(1)NAME
sgmldiff - Find differences in the markup of two SGML files
SYNOPSIS
sgmldiff [ options ... ] file1 file2 [ -a | --attributes
| -c [ attributes | nesting | textpos ] | --context [ attributes | nesting | textpos ]
| -s | --statistics
| -h | --help
| -v | --version ]
DESCRIPTION
This perl script allows to determine the structural differences between two SGML files. It compares the files, regardless of what is in
between the tags, to only focus on the markup. Its output is similar to diff(1).
The typical use of sgmldiff is to compare an SGML file with its translation into another language. If the translation was done cleanly,
sgmldiff returns without finding any difference in the markup.
An example of a typical call to sgmldiff is:
sgmldiff english.sgml italiano.sgml
If there are differences in markup between both files, sgmldiff will output a series of differences reports summarized with lines of the
form:
169a164
At line 169 of the first file, line 164 of the second file has been added.
8a12,15
At line 169 of the first file, lines 12 to 15 of the second file have been added.
41d28 Line 41 of the first file has been destroyed, to obtain line 28 of the second file.
63,66d61
Lines 63 to 66 of the first file have been destroyed. to obtain line 61 of the second file.
52c51 Line 52 of the first file has been changed into line 51 of the second file.
5,7c8,10
Lines 5 to 7 of the first file have been changed into lines 8 to 10 of the second line. In addition to those summaries, the lines
of the first file are shown preceeded by '<' and the lines of the second file are shown preceeded by '>".
OPTIONS
Here is the list of actions that can be requested to sgmldiff:
[ -a | --attributes ]
Include the attribute values in the difference tests. Don't set this value if the attributes are likely to be translated. Set this
value if the attributes value shouldn't change between both files. Default is to don't include the attributes in the difference
tests.
[ -c [ attributes | nesting | textpos ] | --context [ attributes | nesting | textpos ] ]
Add more context to the difference. Since every test between the tags is removed before testing the differences, sgmldiff is likely
to resynchronize itself at the wrong place, by thinking the location in both files correspond, while it's not true. By adding more
context to the compared area, such risk is disminished.
The allowed values for the --context option are:
attributes
Take into account the attribute names. The attribute values are controlled by the attributes option.
nesting
Take into account the nesting level of all the compared tags.
textpos
Take into account the position in the text.
[ -s | --statistics ]
iPrint some SGML information at the end.
[ -h | --help ]
Print a short help message and exit
[ -v | --version ]
Print the version identifier and exit
