无法从 Jenkins 作业中运行的 shell 脚本解析 aws cli 命令主要版本，但为什么呢？

Question

I'm trying to run the following code:

aws --version | awk '{print $1}' | awk -F/ '{print $2}' | awk -F. '{print $1}'

which should return either 1 or 2 per the major version of aws-cli in the Jenkins node that runs this job.

I also tried including the #!/bin/bash shebang in the beginning of the code but to no avail.

For some reason, no matter what I try, I'm unable to parse the major version digit from the output of aws --version .

This is the output of the job:

[workspace] $ /bin/bash -xe /tmp/jenkins1279490794754365723.sh
+ /usr/local/bin/aws --version
+ /usr/bin/awk '{print $1}'
+ /usr/bin/awk -F/ '{print $2}'
+ /usr/bin/awk -F. '{print $1}'
aws-cli/1.16.198 Python/2.7.16 Linux/4.4.0-1012-aws botocore/1.12.188
Notifying upstream projects of job completion
Finished: SUCCESS

I've tried both absolute and relative path's of the relevant commands but no matter what I get the full output of aws --version rather than just the parsed output.

Any idea why?

尝试更新 awk/gawk 并重新运行您的脚本。
