的bash内部命令的来源,首先查找在PATH文件名,除非有斜线(/在文件名)。xset是您PATH中的可执行文件,因此出现了问题。
您可以使用以下命令执行source ./xset或将sourcepath选项更改为off:
shopt -u sourcepath
从bash手册页:
source filename [arguments]
Read and execute commands from filename in the current shell
environment and return the exit status of the last command exe‐
cuted from filename. If filename does not contain a slash, file
names in PATH are used to find the directory containing file‐
name. The file searched for in PATH need not be executable.
When bash is not in posix mode, the current directory is
searched if no file is found in PATH. If the sourcepath option
to the shopt builtin command is turned off, the PATH is not
searched. If any arguments are supplied, they become the posi‐
tional parameters when filename is executed. Otherwise the
positional parameters are unchanged. The return status is the
status of the last command exited within the script (0 if no
commands are executed), and false if filename is not found or
cannot be read.
xset。尝试source ./xset。
