[英]Issues while create a file in shell scripting in jenkins pipeline script
我正在嘗試使用以下命令在Jenkins管道腳本中創建多行文件。
sh "echo \"line 1\" >> greetings.txt"
sh "echo \"line 2\" >> greetings.txt"
echo "The contents of the file are"
sh 'cat greetings.text'
sh 'rm -rf greetings.txt'
不幸的是,我無法創建名為greetings.txt的文件。 任何人都可以讓我知道我要去哪里了。
Jenkins控制台中的結果:
[tagging] Running shell script
+ echo 'line 1'
[Pipeline] sh
[tagging] Running shell script
+ echo 'line 2'
[Pipeline] echo
The contents of the file are
[Pipeline] sh
[tagging] Running shell script
+ cat greetings.text
cat: greetings.text: No such file or directory
任何的意見都將會有幫助。
謝謝!
它沒有找到一個名為greetings.text
的文件,因為您沒有創建一個文件(cat行擴展名中的拼寫錯誤)。 嘗試sh 'cat greetings.txt'
,甚至可以更好地調整腳本:
sh "echo \"line 1\" >> greetings.txt"
sh "echo \"line 2\" >> greetings.txt"
echo "The contents of the file are"
sh 'cat greetings.txt'
sh 'rm -rf greetings.txt'
如果要使用多行命令,還可以使用以下語法:
sh """
echo \"line 1\" >> greetings.txt
echo \"line 2\" >> greetings.txt
echo "The contents of the file are:"
cat greetings.txt
rm -rf greetings.txt
"""
在上一個示例中,這應生成類似以下的輸出:
Running shell script
+ echo 'line 1'
+ echo 'line 2'
+ echo 'The contents of the file are:'
The contents of the file are:
+ cat greetings.txt
line 1
line 2
+ rm -rf greetings.txt
這可以通過在sh
使用單引號來解決,因此您無需使用轉義。 另外,您還必須使用>
創建初始文件,並使用>>
添加內容:
pipeline{
agent any
stages{
stage('write file'){
steps{
sh 'echo "line 1" > greetings.txt'
sh 'echo "line 2" >> greetings.txt'
echo "The contents of the file is"
sh 'cat greetings.txt'
sh 'rm -rf greetings.txt'
}
}
}
}
輸出:
[test] Running shell script
+ echo line 1
[Pipeline] sh
[test] Running shell script
+ echo line 2
[Pipeline] echo
The contents of the file is
[Pipeline] sh
[test] Running shell script
+ cat greetings.txt
line 1
line 2
[Pipeline] sh
[test] Running shell script
+ rm -rf greetings.txt
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
