What is batch scripting in linux

How to run batch file in linux

If the windows box has a web server, you could write a CGI, and trigger it using wget or cURL. Solution 3: Our build process currently goes the other way: a windows sever kicks off things on the Linux server using plink (part of PuTTY). Depending on how precise your timing needs are, you might be able to have an «at» job on the windows box that runs periodically (every 5 minutes?) and runs if it sees that a particular file exists, deleting the file.

How to run process from batch script

Debian uses systemd to manage processes. You should, therefore, use the systemd’s commands to stop and start rsyslogd .

If you are using really old versions of Debian (so old that you should upgrade), it may be possible that sys V is still used. In that case, there is a file under /etc/init.d which is called rc.rsyslog or something comparable (use ls /etc/init.d to find the exact name). In that case, it would be

sudo /etc/init.d/rc.rsyslog stop 

sudo /etc/init.d/rc.rsyslog start 

Or it may be, that your systemd -package may be broken. In that case, the package can be re-installed:

apt-get --reinstall install systemd 

If you want to do both, use

 systemctl restart rsyslog

Linux run command from file in batches

GNU xargs

Other xargs

How to debug xargs ?

I would suggest use your favorite programming language to debug. Mine is Ruby, for example:

node -e 'console.log(process.argv)' 

Put the above commands between xargs and the command you want to execute, for example:

xargs -n1 -P100 ruby -e 'p ARGV' bash -c < input.txt 

["bash", "-c", "-v"] ["bash", "-c", "curl"] ["bash", "-c", "-XPOST"] ["bash", "-c", "-H"] ["bash", "-c", "https://httpbin.org/post"] ["bash", "-c", "-v"] ["bash", "-c", "-d"] ["bash", "-c", "Content-type:application/json"] ["bash", "-c", "curl"] ["bash", "-c", ""] ["bash", "-c", ""] ["bash", "-c", "-H"] ["bash", "-c", "Content-type:application/json"] ["bash", "-c", "-XPOST"] ["bash", "-c", "-d"] ["bash", "-c", "https://httpbin.org/post"] ["bash", "-c", "curl"] ["bash", "-c", "-v"] ["bash", "-c", "-XPOST"] ["bash", "-c", "-H"] ["bash", "-c", "Content-type:application/json"] ["bash", "-c", "-d"] ["bash", "-c", ""] ["bash", "-c", "https://httpbin.org/post"]z 

xargs -d '\n' -n1 -P100 ruby -e 'pp ARGV' sh -c < input.txt 

["sh", "-c", "curl -v -XPOST -H \"Content-type:application/json\" -d '' http://localhost:8080/v1/SomeEndPoint"] ["sh", "-c", "curl -v -XPOST -H \"Content-type:application/json\" -d '' http://localhost:8080/v1/SomeEndPoint"] ["sh", "-c", "curl -v -XPOST -H \"Content-type:application/json\" -d '' http://localhost:8080/v1/SomeEndPoint"] 

If each line is a fully constructed command, xargs is the wrong tool.

sed -n 1,100p inputFile | while read line; do eval "$line"; done

sed -n 1,100p inputFile | while read line; do echo "$line" | sh; done

Certainly not the most elegant solution, but it could work:

input_file=test.sh batch_size=100 nlines=$(wc -l $input_file | cut -f 1 -d ' ') for i in $(seq 1 $batch_size $nlines); do for j in $(seq $i $((i+batch_size))); do line="$(sed -n $p $input_file)" eval "$line" & done wait done 

It takes batches of n lines and executes them individually in the background with eval . After each batch, it waits for each background process to terminate ( wait ).

Invoking windows batch file from Linux

You could install an ssh server in the windows box (Cygwin has one), then from linux do something like:

ssh user@windows-box c:/path/to/batch.cmd 

and that should launch your application in the windows box.

The most direct way is probably to install an ssh server on the windows box. Cygwin includes an ssh server.

Depending on how precise your timing needs are, you might be able to have an "at" job on the windows box that runs periodically (every 5 minutes?) and runs if it sees that a particular file exists, deleting the file. Then you could use Samba/smbclient to create the file. You would need to turn on filesharing on the windows box for this to work.

If the windows box has a web server, you could write a CGI, and trigger it using wget or cURL.

Our build process currently goes the other way: a windows sever kicks off things on the Linux server using plink (part of PuTTY). You might be able to set something similar up.

How do I create a batch file and run it? [duplicate]

Your question is more likely to receive useful answers if it contains some specifics. Such as what type of data is to be processed, including realistic examples of input and output.

@SergiyKolodyazhnyy The duplicate nominee is closed as too broad. As such the close vote on this one should be "too broad" as well. That said it seems like a reasonable question to me as I was once in the dark myself 🙂

@WinEunuuchs2Unix It is closed but does have an accepted answer, which will give OP what they want, or at least a starting point.

@EliahKagan If a mod agrees perhaps he can reopen that one and then merge the answers from here to there?

@WinEunuuchs2Unix That question, which this received close votes to be duped to, was actually reopened a few hours ago, then closed again as duplicate of that highly voted question. Both of them are listed as "originals" in the duplicate banner here (i.e., this question is duped to both of them). So if answers are to be merged, they'd probably be put there. Do you think that would be useful?

To create one use the .sh extension but it doesn't really matter but it helps future users to quickly determine which file type it is. The bat name is mostly used on Windows but in Linux file name extensions do not really matter. Meaning I can call my file say run.de and it would still run in bash file but I believe it's a good practice to name them with the .sh file extension.

For the editor, part uses any that is best for you between nano vim gedit emacs , but I believe gedit would be nice to start with.
