[linux] Execute combine multiple Linux commands in one line

I am trying to merge multiple linux commands in one line to perform deployment operation. For example

cd /my_folder
rm *.jar
svn co path to repo
mvn compile package install

You can separate your commands using a semi colon:

cd /my_folder;rm *.jar;svn co path to repo;mvn compile package install

Was that what you mean?

You can use as the following code;

cd /my_folder && \
rm *.jar && \
svn co path to repo && \
mvn compile package install

It works...

I've found that using ; to separate commands only works in the foreground. eg :

cmd1; cmd2; cmd3 & - will only execute cmd3 in the background, whereas cmd1 && cmd2 && cmd3 & - will execute the entire chain in the background IF there are no errors.

To cater for unconditional execution, using parenthesis solves this :

(cmd1; cmd2; cmd3) & - will execute the chain of commands in the background, even if any step fails.

To run them all at once, you can use the pipe line key "|" like so:

$ cd /my_folder | rm *.jar | svn co path to repo | mvn compile package install

I find lots of answer for this kind of question misleading

The following code will create bash window and works exactly as a bash window. Hope this helps. Too many wrong/not-working answers out there...

            Process proc;
            try {
                //create a bash window
                proc = Runtime.getRuntime().exec("/bin/bash");
                if (proc != null) {
                       BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
                       PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(proc.getOutputStream())), true);
                       BufferedReader err = new BufferedReader(new InputStreamReader(
                       proc.getErrorStream()));
                       //input into the bash window
                       out.println("cd /my_folder");
                       out.println("rm *.jar");
                       out.println("svn co path to repo");
                       out.println("mvn compile package install");
                       out.println("exit");
                       String line;
                        System.out.println("----printing output-----");
                          while ((line = in.readLine()) != null) {
                             System.out.println(line);
                          }
                          while((line = err.readLine()) != null) {
                             //read errors
                          }
                          proc.waitFor();
                          in.close();
                          out.close();
                          err.close();
                          proc.destroy();
                }

            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

If you want to execute all the commands, whether the previous one executes or not, you can use semicolon (;) to separate the commands.

cd /my_folder; rm *.jar; svn co path to repo; mvn compile package install

If you want to execute the next command only if the previous command succeeds, then you can use && to separate the commands.

cd /my_folder && rm *.jar && svn co path to repo && mvn compile package install

In your case, the execution of consecutive commands seems to depend upon the previous commands, so use the second example i.e. use && to join the commands.

What is the utility of an only one Ampersand? This morning, I made a launcher in the XFCE panel (in Manjaro+XFCE) to launch 2 passwords managers simultaneously:

sh -c "keepassx && password-gorilla"
or
sh -c "keepassx; password-gorilla"

But it does not work as I want. I.E., the first app starts but the second starts only when the previous is closed

However, I found that (with only one ampersand):

sh -c "keepassx & password-gorilla"

and it works as I want now...

cd /my_folder && rm *.jar && svn co path to repo && mvn compile package install
