Question

我在/etc/profile.d /

中放置了一个脚本

# default_dba.sh
if  groups | grep -qw "dba" ;
 then 
if [ $USER != "oracle" ]; then
. /u00/scripts/oracle_alias
fi
fi

如果LDAP用户是dba组的成员，则scipt设置别名。这可行。 LDAP用户启动python脚本。最后一步，python脚本调用了一个新的bash shell

subprocess.call(['/bin/bash', '-i'], shell=True)

在该shell会话中，缺少特殊的别名（由/ u00 / scripts / oracle_alias脚本创建），仅存在默认的os别名。

我可以在不为LDAP用户创建主目录的情况下解决此问题吗？

仅当将外壳程序作为“登录”外壳程序调用时，启动文件（在/ etc / profile等下）才是只读的。例如：-bash -l </ p>

有关更多详细信息，请参见man bash下的“ INVOCATION”部分。

摘要（来自手册页）

When  bash  is  invoked  as  an  interactive  login  shell, or as a non-interactive shell with the --login option, 
it first reads and executes commands from the file /etc/profile, if that file exists.  
After reading that file, it looks for ~/.bash_profile,  ~/.bash_login, and ~/.profile, in that order,
and reads and executes commands from the first one that exists and is readable.
The --noprofile option may be used when the shell is started to inhibit this behavior.

在python中使用子进程调用bash时缺少别名设置
