I'm playing with perl and found that I could just go:
"perl /home/me/bash_script.sh"
and it would execute, even though it's not a perl script. Is that just a feature or is there something I'm missing? Why does perl do this?
I can not make this work: I can send email from bash with this script: #!/bin/bash echo "Test message" | /usr/bin/mail -s "test2" "myEmail@yahoo.com"
When I am trying to run this in Perl using system function like this:
#!/usr/bin/perl
system("'Test message' | /usr/bin/mail -s 'test2' 'myEmail@yahoo.com');
I get message that program exited with code 0 , which is nice, but mail does not get to destination.

It has permissions rwxr-xr-x and is not owned by root. Am I overlooking something?
I'm writing a bash script that executes a few perl scripts. One of the perl scripts that I need to execute requires two arguments with it. The arguments are stored in a txt file, each line contains a hostname and its corresponding IP address separated by a ":" (colon), the txt file looks like this below:
[Code]...
I'm not sure if it's the best way to accomplish this but here it goes. In the bash file, let's call it getHosts.sh, I create an array and assign each line of the file to an element in that array. I then think I need to create a new array where I take the hostname (which is before the ":") separate it from its IP address and place the IP address on a new line just below the hostname (this way I can reference to it like $hostNames[$x] would be the hostname, and $hostNames[$x+1] would be its IP address). So the new array would now look like this below:

I want to execute a bash script in a C program. Bash script return some message and I want to store this message in a C program. Anybody know how can I do it.
I know I can use 'system("bash myscript.sh")' command in C. But I want to store the message which script return.
I wrote this script for bash & perl. If you run it in bash it should work. It changes title - (uuid) kernel - initrd ... to title - uuid UUID=the_uuid... kernel - initrd .... When I wrote it I replaced end of lines by . It's the second $block definition. But now I need to repair it, because I will work with the 1st $block definition. That is not to exclude end of lines, but leave it be untouched. Now when you escape the second $block definition, the code does not work. What I have to do to repair it working with multiline input data?
Code:
block="title Sata Mandriva

What i want to achieve si simple (i think).
I have this shell command:
Code:
echo -e 'ka 0 00
' > /dev/ttyS0
and i want to execute it from html or php with a button maybe or a link.(it's a command to turn off the monitor)
I am running Ubuntu 9.04 desktop with apache and php installed .
already searched the forum but didn't find/understand how to achieve this functionality.
I'm trying to start bash with a command and have it interactive like this:bash -i -c "echo Welcome!"As in, execute the command and allow me to use it as an interactive shell afterwards. (I'm doing something more complicated than echoing, but this doesn't work.)I've tried this from a running gnome-terminal, from one gnome-terminal to a new one withgnome-terminal and from the Alt+F2 program launcher (with "Run in terminal" ticked).

Let say I want to create new file with the output of first column and do something else with the output of 3rd column. Of course there are many ways to process this data file, but I wish to know by using awk, how could I do it. I'm trying:
Code:
awk '{system("touch $1")}' datafile
but the shell command will not able to get the awk '$1' output. How do I get this done ? And for another question, if the data file contains the variable name of a shell variable, how could I make use of it during a awk output ? For example I have a datafile1:

server1 yes
server2 no
And in another server declaration data file, I got this datafile2:

server1=xxx1
server2=yyy1

I wanted to run bash and perl scripts which requires SU privileges by clicking on desktop
Terminal window opens and closes fast without knowing what happened.
scripts work on terminal window by telling
sudo perl file.pl
sudo bash file.sh
Perl has this header
#!/usr/bin/env perl
or
#!usr/bin/perl -w
Bash has header
#!/bin/bash
How can I run them with desktop shortcuts with SU privilege so, the terminal will not close after execution? Should not the scripts work without telling perl or bash, since they have the header?
I've been trying to figure out a way to more easily color text in Perl like I do on Bash on a Linux box. In bash, what I'll do is set color variables up to equal the escape sequence, then echo out with escape seqeunces to print it exactly how I want it. Typically I'll want a character or a word in a different color, not the whole line. For example
echo -n -e "My face is turning ${RED}red${UNCOLOR} like a lobster." In Perl with the term::ANSIColor module, it seems to just do a line. Am I being dense? Is there a way that I can do it like I do it in BASH that's fairly easy to read after the fact?

I've recently inherited a bunch of files at a new job and am trying to figure out some of the problems that have constantly popped up. The one i'm getting a huge headache with results from a bash script that is supposed to change a date format from a client populated txt field to one we want defined a certain way. Everything in the script works fine, except that one function. Below is the line i'm trying to manipulate, with date examples.
sed -e 's/.0000 EA/ EA/' -e 's/ 01012010 / 01-JAN-2010 /' -e 's/ 12312011 / 31-DEC-2011 /'
The one caveat is that the first date is non-static and changes daily. It is, however, always the current date. If it helps, the second date will always be a year away from the first date.My idea was to pull the current date via perl's DATE function, but...how to do it, and calculate a year away without throwing the rest of the bash script off? Any help would be appreciated. I'm sure it's a simple solution but i know absolutely nothing about these scripts and how they were written.
pretty simple. how would you background a process from a script and get its process id at the same time?
View 6 Replies View RelatedThis pretend to be a script for rename a lot of files automatically. So I put the list of files in an array named @lista. But, as you can see, at the end of the command I use a sed filter to print out a backslash for those files that have spaces in their names, so the path for those files could be rightly interpreted.
But there's no way I could print a backslash. It works well when I use the Perl's sed substitution s///, but I need every path in the array to be fixed.
I'd like to add that the bash command works perfectly well alone. I mean outside the Perl script.
This is de command line with the sed filter:
