问题
I am quite new to the Mac Terminal environment. I donwloaded sqlplus (which is recognised as a UNIX executable program) and then in Terminal I do cd a few times until I arrive in the folder I put this in (\Applications\instantclient_10) in this case. When I type 'ls' I see a listing of all the files including the sqlplus. So I would then expect to simply type at the Telnet prompt 'sqlplus' and then this would start but instead keep getting
-bash: sqlplus: command not found
This is problem one.
I have now downloaded MySQL and again, when I go to the correct folder (\Library\StarupItems\MySQLCOM) and I type 'ls' I see my files (including MySQLCOM) but when I come to try to 'run' this by simply typing 'MySQLCOM' again the message is:
-base: MySQLCOM: command not found
What am I doing wrong? Thanks
回答1:
To run binary/executables in current folder you need to prefix them with ./
./sqlplus
The idea here is that you want to force execution of local file and not run it accidentally. Imagine app that would put ls binary into it's folder and it would automatically run if did ls in that folder.
