使用一个bash脚本在diff目录中执行多个bash脚本

Question

I have multiple bash scripts to bounce Jboss instances in multiple directories. These scripts accepts arguments

start | stop | reload | status | restart.

 /opt/xyz/x/X_FE.sh 
 /opt/xyz/x/X_BE.sh
 /opt/xyz/y/Y_FE.sh
 /opt/xyz/y/Y_BE.sh
 /opt/xyz/z/Z_BE.sh

I wish to have a single bash script which accepts the same arguments and execute all the 5 scripts mentioned above.

/opt/singlescript.sh start ---- must execute all the 5 scripts with start argument.

Any help would be much appreciated.

Answer 1

It would look something like this. There are multiple ways to do this and this is just one way

#!/bin/bash
echo "invoking x/X_FE with $1"
sh /opt/xyz/x/X_FE.sh $1

echo "invoking x/X_BE with $1"
sh /opt/xyz/x/X_BE.sh $1

echo "invoking y/Y_FE with $1"
sh /opt/xyz/y/Y_FE.sh $1

echo "invoking x/Y_BE with $1"
sh /opt/xyz/y/Y_BE.sh $1

echo "invoking z/Z_FE with $1"
sh /opt/xyz/z/Z_BE.sh $1

Answer 2

Using GNU Parallel it looks like:

parallel ::: /opt/xyz/x/X_FE.sh  /opt/xyz/x/X_BE.sh /opt/xyz/y/Y_FE.sh /opt/xyz/y/Y_BE.sh /opt/xyz/z/Z_BE.sh ::: start
parallel ::: /opt/xyz/x/X_FE.sh  /opt/xyz/x/X_BE.sh /opt/xyz/y/Y_FE.sh /opt/xyz/y/Y_BE.sh /opt/xyz/z/Z_BE.sh ::: stop

If they cannot be run in parallel add -j1:

parallel -j1 ::: /opt/xyz/x/X_FE.sh  /opt/xyz/x/X_BE.sh /opt/xyz/y/Y_FE.sh /opt/xyz/y/Y_BE.sh /opt/xyz/z/Z_BE.sh ::: start
