[英]BASH_VERSION is empty even though SHELL is /bin/bash
I have run into an issue when executing script in /etc/profile.d/script.sh. 在/etc/profile.d/script.sh中执行脚本时遇到问题。 On one of my machines (only this one, on the others it is running well), when I do 在我的一台机器上(只有一台机器,在其他机器上运行良好)
echo "$BASH_VERSION" >> /home/synek317/log
echo "$SHELL" >> /home/synek317/log
the result is that BASH_VERSION
is empty, but SHELL
is /bin/bash
. 结果是BASH_VERSION
为空,而SHELL
是/bin/bash
。 However, when I run terminal and type echo $BASH_VERSION
, it is filled correctly. 但是,当我运行终端并键入echo $BASH_VERSION
,它将正确填充。
I run this on Ubuntu 16.04.1. 我在Ubuntu 16.04.1。
Do you have any ideas why is this variable empty during execution of /etc/profile.d/
scripts? 您有什么主意,为什么在执行/etc/profile.d/
脚本时此变量为空?
根据定义,/ /etc/profile.d
脚本不是由Bash运行的。
