问题 I have a fixed length string which is a number. When I assign the string to a variable it is getting assigned 8 instead of 10. Why? How do I stop it? $ i=10 $ ((i=i+1)) $ echo $i 11 # Right answer $ i=000010 $ ((i=i+1)) $ echo $i 9 # Wrong answer Update: The answers confirm that the number is being converted to octal and that the leading zeros need to be removed. Here is the sed command for that. echo "000010" | sed 's/0*//' 回答1: That's because a leading 0 means that the constant is octal

问题 I am working on an automated backup script. This script needs to download an HTTP resource using a username and password. At the moment, the auth credentials are in cleartext, which is obviously not ideal from a security point of view. I recently discovered the security utility on OS X after reading this blog post. security gives you keychain access from the command line. The OS X Keychain allows you to specify applications that are allowed access to a specific password, but it turns out that

问题 I have a lua script that needs to call a zunionstore on a variable number of keys.

问题 I am working on a project where I need to modify a script used for network documentation. The current script that we use is a modified version of SYDI, found here. What I would like to do is add to this script the ability to execute a netstat -an and have it returned with the rest of the report. I was curious if anyone has used WMI and VBScript to return netstat information and how it might be able to be incorporated into this script. NOTE: I am not trying to promote a product and I am not

问题 How to run database scripts(MySql db scripts) in c#. Thanks, sirni. 回答1: Fork a child process and execute the mysql command-line client, using the script as input. It's tempting to try to read the script as a file and execute the SQL commands within it one by one, but there are numerous statements in an SQL script that can't be executed that way. So you'd have to duplicate the code of the mysql client anyway in order to run an SQL script. Do yourself a favor and use the program that is

问题 some short and probably stupid questions about PBS: 1- I submit jobs using qsub job_file is it possible to submit a (sub)job inside a job file? 2- I have the following script: qsub job_a qsub job_b For launching job_b, it would be great to have before the results of job_a finished. Is it possible to put some kind of barrier or some otehr workaround so job_b is not launched until job_a finished? Thanks 回答1: Answer to the first question: Typically you're only allowed to submit jobs from the
