i'm trying to create a shell script so that it calls two commands in 2 seperate directories and then shows their feedback, To call the a command i'm guessing it would be something like this ./directory/ ./script.sh
Thanks in advance for your replies.
If you want to sequentially invoke the commands:
/path/to/command1; /path/to/command2
If you want to call the second command only if the first one succeeded:
/path/to/command1 && /path/to/command2
If you want to run them in parallel:
/path/to/command1 &
/path/to/command2
The output of the commands will be the standard output (most likely the terminal). If you run the two commands in parallel and they produce some output, you might want to redirect it to different files.

I am trying to write a wrapper script that calls other shell scripts in a sequential manner
There are 3 shell scripts that pick .csv files of a particular pattern from a specified location and process them.
I need to run them sequentially by calling them from one wrapper script
Let's consider 3 scripts
a.ksh, b.ksh and c.ksh that run sequentially in the same order.
The requirement is that the script should fail if a.ksh fails but continue if b.sh fails.
Please suggest.
Thanks in advance!
Something like:
./a.ksh && ./b.ksh; ./c.ksh
I haven't tried this out. Do test with sample scripts that fail/pass before using.
See: http://www.gnu.org/software/bash/manual/bashref.html#Lists
I have two scripts which are to be executed and i am using Windows batch script for automating of running the scripts.
I have to read 10 user input values and then run the two scripts using those parameters.
I am successful in executing the first script and failing with the second script.
Issue is that the cmd prompt exits after completing the first script.
How to make cmd prompt run the second script as well using the input parameters.
Any Help on this??
Thanks in Advance.
You have two options to execute a batch script from you code. It's either START or CALL:
START will execute your code in it's own variable scope, means the variables you've set in the first script won't be available. Further both scripts will be executed in parallel and not one after another (unless you use START /WAIT).
CALL on the other hand will do exactly what you need. It will start the first script in the same scope (previously set variables are variable), execute it and afterwards it will run the second sript (also in the same scope).
TL;DR this will work:
...
CALL BatchScript1.bat
CALL BatchScript2.bat
...
If you call scripts from another script you have to use the call command:
#echo off
call first.cmd
call second.bat
echo Here I'm back again !
I have a batch file (build.bat) which calls a bash script (makelibs.sh). The bash script contains several commands which build 20 libraries from source.
If I run makelibs.sh from MSYS, I get continuous output. If I call it from the batch file, then I see the full output only at the end of every single command.
This makes it difficult to assess the current status of the process.
Is it possible to redirect the output of makelibs.sh in order to get a continuous feedback on the execution?
I have a batch file (build.bat) which calls a bash script (makelibs.sh)
I strongly advise against doing this. You are calling a script with a script, when you could simply open up Bash and put
makelibs.sh
However if you insist on doing this then perhaps start would work
start bash.exe makelibs.sh

Is it possible to set a cmd.exe shell / batch file to print what would be executed but not actually execute it?
For example, given a batch file that takes some arguments, based on those arguments selects some other batch files to run, those batch files execute some commands, may or may not call other files/commands etc.
I would like to be able to run the top level batch file with all possible combinations of it's input arguments and capture what each arg combination would execute - without actually trying to execute it.
e.g. conceptually would want to be able to produce something like:
mybatchfile.bat 1 2 3 > mybatchfile_1_2_3.bat
mybatchfile.bat 99 3 42 > mybatchfile_99_3_42.bat
where mybatchfile_99_3_42.bat is the list of everything that WOULD be executed when running mybatchfile.bat 99 3 42 (NOT the output of executing those commands)
If this can't be done solely using cmd.exe is there someway to achieve this by running the batch script in cygwin bash shell
In bash we would use something like -x to print out all possible commands without executing them. how to make bash scripts print out every command before executing The problem is that to my knowledge there's no exact equivalent command for Batch Scripts. I would suggest you try placing:
#echo on
at the beginning of your script and:
#echo off
at the end of your script, that's the best starting place.
If you never want the batch file to actually execute the commands, you can insert echo before each command. It's not a perfect solution by any means, but it may be a work-around for fairly simple scripts.
I have a question regarding the creation of a utility that executes another command.
My script called notify will be placed in my /usr/local/bin directory and will do the following:
Execute the command that it was told to execute, then play a beep.
An example use case is the following:
> notify grep -r "hard_to_find_word" /some/huge/directory/
This is just an example, but could involve some other slower commands.
Essentially, notify will execute the grep, and then play a sound.
I know how to play a sound, but I do not know how to execute the provided command.
How do I execute the command that follows the call of notify?
Thank you for any input!
