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 am running a command pretty similar to the one below:
Code:
I need to capture the exit status of that part of the command.
What I am trying to do is set a variable that can be modified within my_job.sh, and used to exit.
However, no matter what I set "status" to in my_job.sh, it exits with "0".
What can I do differently?
How exactly can I use the exit status of a command in an if statement ?
Something like this:
Code:
I am setting some environmental variable in my .bashrc , the sample code I was provided with is for CSH but I am using bash, and there are some syntax differences between them ... I got most of the script to work, but I am getting an error at this part :
Code: if ($RMSTREE == $RMANTREE) then
set path=($path $RMANTREE/bin)
else
[code]...
Is there a way to count the number of errors- an exit variable $? from one function?
The output from the exit variable (either erroneous or correct (1) or (0)) is it possible to add the erroneous one ups?
I have this project which I've been working on essentially nonstop for the past three days and due to work I am running low on time. I'm new to Linux/Unix and my Teacher has assigned us a scripting project, due for Monday. I have All the functions for the project in a separate file which run as a daemon process when I log in. It has no syntax errors but my Script can not run the functions (I'm not sure where they go before or after the body) and I have one function I'd like you guys to take a look at. It has a Second menu leading to a case statement but it does not run after the Search. I'm Kinda tired of looking at the CLI but I have to finish this.

I do not understand bash' syntax regarding the use of ((<arithmetic expression>)). $((<arithmetic expression>)) is tokenised to a single word. OK.
Code:
In isolation
Code:
It may not be used where a word is expected. This generates a syntax error. Why?
Code:
I have a daemon script which wakes up every 5 minutes and checks the health of started processes. It works fine during the day but throws a syntax error just after midnight.Here is the log:
(02/22-23:49) Check all started processes
(02/22-23:54) Check all started processes
(02/22-23:59) Check all started processes

I have not been able to write bash to use a PID file to ensure no other instance of the same script is running! All three methods I can think of to see if the PID in the PID file is another instance of the script make the script exit with a return code of 1 but the same commands run at the command prompt work as expected.
The first attempt was:
Code:
The first attempted workaround was:
Code:
The second attempted workaround (with debug to make the following command prompt copy and paste meaningful) was:
Code:
Here's the command prompt session, testing with a stale PID file and then manually running the problem command and it behaving as expected:
Code:
This on Slackware64 13.1 which has bash 4.1.7.
In desperation I tried rebooting but the behaviour was the same.

I am trying to get bash script using zentity to exit if the user presses the cancel or close buttons.The exit codes are working fine; they read 1 or 0 depending on the status but it always assumes 0. This is the portion of the script: PHP Code:

I am a Novell (now defunct) CNE tring to learn Linux and am having a lot of trouble finding out where the WB 6-6 is wrong in the syntax for adding local4... the the syslog-ng config file. In the instructions there are discrepancies between commas and simi-comma, they are both in the statements in no particular order. there is no pattern to them. Here is what the book shows:
filter f_local4debug { level(debug) and facility(local4); };
When I try to input this in the Gnome terminal window to try and find out where it goes wrong I get the following: -bash: syntax error near unexpected token "(" If I can get the correct syntax I belive I can use the info to get past the rest of this portion of the lesson. I am desperate to learn Linux as the only jobs out there for a Novell CNE are migrations to MS, which really sucks, since MS really really sucks.
I noticed that if I have "exit" in a bash script file., e.g. script.sh,that when the word "exit" is reached, and the script file being executed is not in the PATH nvironment, i.e. ". script.sh", the whole konsole shell profile is exited! What gives here? Is there another command compatible to "exit" to prevent this, or will I just have the leave the "." part in the PATH enviroment, which is, to my understanding, is not recommended? I desire for a "goto" function in bash script files
View 11 Replies View RelatedI 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.

In linux, creating thread is same as process (clone()), except the virtual address space gets shared with the parent.If a running main process(thread) creates new thread, and if main thread exits, why should the new thread too exit? both are different entities, The same doesn't happen if the child thread exits, the parent thread would be alive.

I would like to make a one-liner, which diff's "ps aux" output before and after killing a process. So basically it should be a combination of fallowing commands:
1) diff -u
2) ps aux | awk '{print $2}'
3) kill `ps aux | grep [c]ron | awk '{print $2}'`
4) ps aux | awk '{print $2}'
How to achieve this? Something like this:
Code:
diff $( kill `ps aux | grep [c]ron | awk '{print $2}'` && ps aux | awk '{print $2}' ) $( ps aux | awk '{print $2}' )
I don't have pgrep or pkill available.
I'm writing a script using ksh that diffs two dirs that contain about 30 files, and writing the results on a logfile. When files differ, it writes the difference with no problem, but I also need the script to write a message if no differences are found.

[ -d FILE ]True if FILE exists and is a directory.
[ -e FILE ]True if FILE exists.
[ -f FILE ]True if FILE exists and is a regular file.

In a bash script brought over from a Debian/Lenny system, Ubuntu 10.04 stumbles on the left parenthesis in the expression below:NEED_COLS=$[($HEX_WIDTH * 4) + 12]Is it an Ubuntu/Debian script style mismatch, or just post-Lenny? If that can be answered, is there a way to reconcile or syntax check older scripts?
