执行shell脚本的时候为什么有的时候不加"./"就不能执行呢?

fox_fox

这样执行就会报错
$ exec_t.sh
sh: exec_t.sh:  not found.
而这样才能执行
$ ./exec_t.sh

本来以为在自己的$HOME目录下不用加"./" 但是还是不行呀

请大侠们帮忙解释一下,谢谢了

man bash:

1. 
   
2. After a command has been split into words, if it results in a simple command and an optional list of arguments, the following actions are taken.
   
3. 
   
4. If the command name contains no slashes, the shell attempts to locate it. If there exists a shell function by that name, that function is invoked as described above in FUNCTIONS. If the name does not match a function, the shell searches for it in the list of shell builtins. If a match is found, that builtin is invoked.
   
5. 
   
6. If the name is neither a shell function nor a builtin, and contains no slashes, bash searches each element of the PATH for a directory containing an executable file by that name........
   
7.

provided $HOME is in $PATH ,
try this
export PATH=$PATHHOME

一般勢將 $HOME/bin 加入 PATH.
然後將 program 放進去.
