linux - Perl script in cgi-bin not executing shell script with arguments -

-

My Perl script is present in CGI-bin / relation: There is a problem in this snippet of code: < Pre> system ("./ upd_test.sh $ res_file $ label> log / upload log2 & amp; 1 & amp; - & gt; system does not work (" ./ upd_test .sh "); - & gt; works fine

I do not understand why this is happening, Apache server is used.

File permissions for Perl script are 

  -rwxr-xr-x 1 root Apache1935 Oct File permissions for Shell Script   .sh   
 If I can call Shell Script without arguments, then why is this issue when I call with arguments? The script is not said at all. The script has added a print that writes in the  / tmp  space whether it is executed or not.  
 I just found out that if I remove the redirect, then it works fine, then the system works fine (". / Upd_test.sh $ res_file $ label"), but I redirect the logs I want to do because it is very important for my work.   
 
 
 The current working directory is not your CGI script, so its use / will not work.  
 Try using FindBin () to get the directory or just the full path to the updcode_sht script.  
 But ... the system () is running from CGI scripts (hence, actually from web page) is dangerous.

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
