How to create a text file using variable #984

ChunwenWang · 1 decade ago

HI,
I created a variable named build_comment
Edit Step of Type: Build > Shell/Batch Command
My command is: sudo echo ${vars.get("build_comment")} > abc
I run this configuration and input build comment as "This is build comment xxx "
The log is as follow
Why did it not produce a file abc for me ?
it just show This is build comment xxx >abc in log

Another question:
Can it show in overview?
I mean the variable value, not the file.
I would like to show it in summary table.
If it can do so, I won't create a text file with this variable and publish it.
Now I can do is show it in build version. But it is too long in title.

Just write the command as "sudo sh -c echo ${vars.get("build_comment")} > abc"

ChunwenWang · 1 decade ago

It still does not work for me.
I only set a step named produce build_comment.txt
Working Directory : /works
Others are default value.
Please help.
log as follow

Sorry should be written as below:

sudo sh -c "echo ${vars.get("build_comment")} > abc"

ChunwenWang · 1 decade ago

Thanks. It works well now.
I am a little confused.
Why does it must start with sh -c ?
So should I must start with "sh -c" to my every shell command ?
But I build my code with "sudo make xxx" successfully.
I don't know when to start with "sh -c".

robinshen ADMIN · 1 decade ago

Since "make" is a binary, while "echo" is a sub command interpreted by "/bin/sh"

ChunwenWang · 1 decade ago

Thanks your remind.
I can't input single quote ' or double quote " in my variable build_comment by this way.
Is there any smarter way to fix?
My solution to input single quote in build_comment as follow
sudo sh -c "echo \"${vars.get("build_comment")}\" > abc"
But it still can't input double quote "

robinshen ADMIN · 1 decade ago

Please use script step (misc->execute script) to avoid redirection hassles:
groovy: new File(configuration.workspaceDir, "abc").write("\"" + vars.get("build_comment") + "\"")

ChunwenWang · 1 decade ago

Thanks.
It can work by this way.

Dear Robin,

How to write many variable to one file.
Example:
var1=abc
var2="(/?ab)" -> var2 include some special character.

I want to write var1, var2 to variable.txt
How to make it by groovy script ?

Best Regard,
Nguyen Quoc Vuong

robinshen ADMIN · 1 decade ago

Please use below script to see if it works:

groovy: 
def content = ""
content += "var1="
content += vars.getValue("var1")
content += "var2=";
content += vars.getValue("var2")
new File(configuration.workspaceDir, "vars.txt").write(content)

Thank you Robin.
I make groovy for run linux command:

groovy:
def String cmd = "echo `date +\"%T\"`"
Process p;
def String [] command = ["/bin/bash", "-c", cmd];
p = Runtime.getRuntime().exec(command);

My problem: I want to write the result of procees p to file "vars.txt"

### OR Could you show me the code groovy to write current date and time with format (YYYY/MM/DD hh:mm:ss Ex : 2013/03/07 11:12:00) to file vars.txt

Best Regard,
Nguyen Quoc Vuong

robinshen ADMIN · 1 decade ago

In groovy, use below code to format current date:

new Date().format("YYYY/MM/DD hh:mm:ss")

Then you can write the result to text file as usual.

quoc.vuong · 1 decade ago

Dear Robin,
I run command in shell
and I want to write the result to file.

Example:
write the result of command "ls -lai" to file result.txt
Could you show me the code groovy to implement that.

Thank you so much.
Best Regard,
Nguyen Quoc Vuong

Hi,
Try this please:

groovy:
new File(configuration.workspaceDir, "file.txt").text = "ls -lai".execute().text
