Run your own shell script

Shell scripts can be directly./**.sh, or bash **.sh

I use the./**.sh to run a script of my own, and the following error will appear:

[Email protected]:~$./pixel. SH bash:. /pixel. SH : Insufficient permissions [email protected]: sudo ./pixel. SH [sudosudo:./pixel. sh: no command found

But running bash **.sh can.

./**.sh is the execution of the script as an executable and requires the chmod to change the permissions.

Save the above code as test.sh and CD to the appropriate directory:

+./test.  #使脚本具有执行权限./test.  #执行脚本      

Note that it must be written ./test.sh, not test.sh, run other binary programs also, write directly test.sh,linux system will go to the PATH to find there is no test.sh, and only/bin,/ Sbin,/usr/bin,/usr/sbin, etc. in path, your current directory is usually not in the path, so write test.sh will not find the command, to use./test.sh tells the system that it is looking in the current directory.
