问题 I'm trying to use perl as my web server for a specific address:port number, 10.x.x.x:portNumber, while also having it show what's in my index.html file by default. However, perl does not show the contents of index.html when I run 10.x.x.x:portNumber in my browser. How can I get perl to read from a file? This is the code I'm working with for this problem. #!/usr/bin/perl { package MyWebServer; use HTTP::Server::Simple::CGI; use base qw(HTTP::Server::Simple::CGI); my %dispatch = ( '/' => \&resp

问题 Hi I am unable to run the .sh file using my php code. Files: index.php and .sh files are in the same directory.

问题 I'm tasked with a making a shell script that swaps 2 strings and then outputs a file. The commands are similar to: sed s/ search_for / replace /g output.txt > temp.dat mv temp.dat output.txt The script works like this: ./myScript var_A var_B output.file Which I got to work fine.

I want to

Per POSIX, sleep only supports integral seconds. It may also not be readily obvious where to test for whether the operation is

问题 I want to replace a variable only if two other variables matches. For Example I have this in my data.txt: Mary Jane:Runs:Pasta Mary Jane:Kicks:Apricot John:Runs:Pasta And I want to replace one variable only on the line which matches with both value. Say I want the first variable to match "Mary Jane" and the second to match "Runs" and then change that particular line from "Runs" to "Sleep", so this should be the result: Mary Jane:Sleeps:Pasta Mary Jane:Kicks:Apricot John:Runs:Pasta But I get

问题 I need to execute "monit restart haproxy" command after sudo su. This is my script.sh sudo su monit restart haproxy. Here if i will execute the script.sh file then it will hang and it is not executing the monit restart haproxy command. Any idea.
