Today, during the installation of the Oracle database, a strange error occurred during the execution of the installation package script, as follows:

[[email protected] test]# sh rpm.sh--word interpretation--ambiguous: ambiguous--redirect: direct: Ambiguous redirect:ambiguous redirect : ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous Redirect: Ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:am Biguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous Redirect:ambi Guous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous Redirect:ambigu ous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous Redirect:ambiguou s redirect:ambiguous redirect:command not Found:command not found:ambiguous redirect:ambiguous redirect:ambiguous re Direct:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous redirect:ambiguous Redi Rect:ambiguous redirect:comMand not Found:command not Found:command not found  

So, we looked at the executed script, which was written in advance to execute the installation package under the win platform, as follows:

Successful execution, compared to two scripts before and after, there is no difference in writing content.

View script permissions, exactly the same as two scripts, hyll.sh can execute normally, while rpm.sh does not execute properly.

Summary:

Today's problems feel a little strange, almost the same two scripts, one can be executed, the other can not be executed. After another experiment, the script was copied exactly the same time (script name, content), without any modification, the script was rebuilt once. The rebuilt script can be executed. Thought, the only difference is that the script that can't be executed is actually written on WINDOWS , and the new script is actually written on LINUX . Although the problem is solved, this phenomenon still feels very strange.

So with curiosity, in the online search "ambiguous redirect" The cause of the error, found that there are many questions about the redirection format. So think about whether the redirect symbol is required to be written under LINUX to perform normally (that is, the Linux system is more sensitive to some special operators).

With doubt, start experimenting again. The general idea is as follows:

Under Linux , the non-executable script can be modified to execute the script (that is, rewrite the instructions under Linux ), export to WINDOWS , replace the LINUX platform, Rename the exported script file and upload it to the experimental platform to verify the availability of the script. After verification, the script edited by the LINUX platform can execute normally, and the script cannot be executed because of the cross-platform writing format. In WINDOWS and LINUX system in which the format of the swap line is slightly different, so today this error tells us that the future modification of the script to be completed under the LINUX system, and then import into their own storage devices, Case.
