我最近在脚本中遇到了一个错误,我尝试执行以下操作:
yum -y install another_package.x86_64 some_package.x86_64 && run_my_script
该脚本在较新的CentOS上运行良好,但当我尝试在Cent OS 5上执行时,some_package.x86_64不可用.但不是错误和停止yum只是打印消息:
No package some_package.x86_64 available.
正如您所发现的,此行为在RHEL 5和6之间发生了变化(有关讨论,请参阅
https://bugzilla.redhat.com/show_bug.cgi?id=736694).从该链接,检查yum info< pkg>的返回代码应该允许您根据需要中止脚本.就像是:
# Set a variable containing the packages to install: pkgs_to_install='another_package.x86_64 some_package.x86_64' # Loop over the packages in the list: for pkg in ${pkgs_to_install}; do # Stop executing if at least one package isn't available: yum info ${pkg} >> /dev/null 2>&1 || exit done # Continue running your original script: yum -y install ${pkgs_to_install} && run_my_script
