General :: Diff The Output Of One Bash Script Against Another?
Jul 6, 2011
I would like to compare the (screen) output of one bash script with the (screen) output of another bash script to ensure the output is exactly the same.The reason for this is that I am receiving a consolidated data feed from an IP address and have moved some of the data feed to a 'new' source IP address. I will turn off the feed from the original once satisfied that the new is receiving the same data. The format of the output from the scripts are exactly the same.
Tried so far
./IDCGRE.sh | grep FX.CK | diff < ./IDCGRE2.sh
./IDCGRE.sh | grep FX.CK | ./IDCGRE2.sh | diff
[code]...

I have a program that writes to stdout. Is there a way that I can redirect the output to the linux diff command or do I have to write the output to a file and then compare that. For example I have a bunch of test input files for a program and the corresponding expected output in another set of files. And I'd like to do something like ./program < t1.input | diff t1.expected.

I'm new to scripting and I have a trouble with if statement syntax. The code is: Code: #there is a diff command here, and it does what i want but#i wanna see 1 if the exit value of diff is 0, and otherwise i wanna see 0.#the problem is here: (syntax error near unexpected token "then")
if["$?"==0];
then
echo 1

I like the output of
Code:
git diff --color-words old..new
but I do not know how to set --color-words permanently in the ~/.gitconfig file.
Edit: I guess I should've said that I do not want an alias for diff --color-words

Now, I have one script called "defcon" defcon gets the current DEFCON level and outputs it using echo.
Code:
#!/bin/bash
DEFCON=`curl -s http://members.tripod.com/~Swat_25/defcon.html | sed -n '/^$/!{s/<[^>]*>//g;p;}' | sed '/^$/d' | grep '[12345]$'`
echo "The current DEFCON level is $DEFCON"
The second script ("tweet") updates my twitter account.
Code:
#!/bin/bash
curl -s -u USER:PASS -d status="$@" http://twitter.com/statuses/update.xml > /dev/null
What I want to do is be able to update my twitter account with the current defcon status (this is really more of a learning thing than something I actually want to be doing). The original script for tweet replaced $@ with $1, but if I use:
tweet `defcon`
it only uses the first word in the string, similarly if I used $2 or $3.So I changed it to $@. The normal function still works, but typing:
tweet `defcon`
updates twitter with nothing.
EDIT I should mention the /dev/null is there to catch the output of curl, otherwise it won't run silently. It still updates twitter normally with the send to /dev/null

I'm having trouble with a bash script. I have something like this:export VAR=`command`The problem is that "command" can return this: "** NONE **". bash will then replace each of the * by the list of files in the current directory.I want the output to be uninterpreted (i.e. VAR should contain "** NONE **", not "list of files list of files NONE list of files list of files"). It shouldn't be hard but I am unable to figure it out, and I'm not sure how to phrase the problem,

I know how to redirect the output of a terminal to a file. For example, if I want to list all the files in ~/Documents and output to a file called test.txt, I would do this: ls ~/Documents > test.txt The question is, can I copy the output to test.txt AFTER I have carried out the command? This would mean that I wouldn't have to know in advance whether I want to copy the output to file. I want to do something like this: ls ~/Documents Then this: <bash command for copying standard output to test.txt>

I'm trying to remember how to use the output of a nested Bash builtin call. So `which prog` gives me the path to the program, i'm interested in. Then I would like to get the directory path leading to that program and plug it into 'cd', so i end up in the directory containing the program.

if I'm posting to the wrong forum. Be so kind to tell me where to better ask this question, as I'm really not finding the right words to google for.So, I have a shell application (fdb) which is a Flash debugger. I want to run it using bash script, capture it's output and pass it the commands (it can read from STDIN). The reason I want to do so is that Flash Builder (the IDE for Flash development) is plain stupid when it comes to compilation, and it won't allow me to compile any file in the project... so, I found out that I can make Eclipse to run an external tool. This external tool is my *.sh file whichches the compiler, and then it launches the debugger.The Eclipse console can display the compilation results, or errors. When I run the debugger it can even pass the input from Eclipse console to the debugger, however, the output from the debugger isn't shown.

I was trying to redirect command output to a variable and realized that all the lines were joined. I tested this additionally with an example:
Code:
echo "The contents of this directory are " `ls -l` > dir.txt
and all the lines were joined in the resulting file. What can I do to preserve separate lines?

I have taken into count spacing of functions as a reason for not working. Can you get this function to work on your machine?
quickfind () { find . -maxdepth 2 -iname "*$1*" }
It does not print the retired output but find . -maxdepth 2 -iname "*$1*" does work. What is wrong?
quickfind () { f
ind . -maxdepth 2 -iname "*$1*" ; }
If I run this from the command line I don't get an error but no output? I am not running this inside a script but from the command line. I want to be able to run any function () from the command line. I have more functions that I can't get to work?
tt () { tree -pFCfa . | grep "$1" | less -RgIKNs -P "H >>> " }

I have to save the result of ssh/grep into a file to keep the eol ("/n"):
ssh $SSH_OPTIONS $USER@$NODE "cd $LOG_DIR; grep -h '$pattern' log.*" > $file
So that when I grep on the local file again later, it can be printed out with original log lines. Otherwise, the log lines will be dropped and lines becomes concatenated into a single line, e.g., if I rewrite the script in this way, echoing the $result is not a good idea..
result=`ssh $SSH_OPTIONS $USER@$NODES "cd $LOG_DIR; grep -h '$pattern' log.*"`
is there some workaround that I can save it to a variable rather than file but still keep the eol? That will simplify my script and don't need to do all those I/Os!
