How do i loop through each line of a file after it has been used as an argument?-CodePudding

I have this script called install-plugins.sh that installs plugins into jenkins.

#!/bin/bash

JENKINS_URL=http://localhost:8080
PLUGINS_FILE=$1

while IFS=':' read -r plugin_name plugin_version; do
  java -jar jenkins-cli.jar -s $JENKINS_URL -auth admin:admin install-plugin "${plugin_name}:${plugin_version}"
done < "$PLUGINS_FILE"

java -jar jenkins-cli.jar -s $JENKINS_URL -auth admin:admin safe-restart

I also have a txt file that has the plugin names and their versions

run-condition:1.5
blueocean-dashboard:1.27.1
blueocean-core-js:1.27.1

Whenever I run the script, the first plugin is only installed but not the others below. How do I fix this?

./install-plugins.sh plugins.txt

Installing run-condition:1.5 from update center

CodePudding user response：

Your java will consume the rest of the STDIN. So,

run-condition:1.5

is read by the while read, and

blueocean-dashboard:1.27.1
blueocean-core-js:1.27.1

is read by java.

A simple solution would be to give java its own STDIN to chew on:

while IFS=':' read -r plugin_name plugin_version; do
  echo 'hoppa' | java -jar jenkins-cli.jar -s $JENKINS_URL -auth admin:admin install-plugin "${plugin_name}:${plugin_version}"
done < "$PLUGINS_FILE"
