Programming :: Scripting/programming Challenge Mac/PC Interoperability?
Jul 27, 2011
some basic programming/scripting/etc. ability but I am not able to do what I now need to do. I would like to have a link on a website that when a user clicked on that link, one script or another would execute based on what operating system that person is using. To wit: If a Mac User clicked on it, it would run a terminal script and would set up a served printer for him; if a PC user clicked on it, it would run a script to set up the served printer on his machine, you get the drift. The printer is being served on a Windows Server 2003 machine, the users are NOT domain users, the print server is also hosting the files, scripts, webpage.

Groovy is an object-oriented programming language for the Java platform. I do not have experience in Java, only perl and shell scripts. Recently I have been asked to maintain a software written in groovy (also to make enhancements). So can I learn groovy without knowing java language. or isit I have to learn java before venturing into groovy.

i'm in the process of learing C++. currently i'm creating shell scripts to get things done. i'm just curious how, as a programmer using C++ you would get a similar job done.as an example i have a script that takes the contents of files, pipes it to some sed and awk commands, which is piped to create a new file. that file is then imported into a mysql database.if you were going to do this in C++, would you call the sed/awk programs to modify the file, or can it be done within the program itself? i'm probably jumping the gun here because i've just started learing about pointers so this is above my ability

I want to know which is the best scripting language right now and what you guys think its going to be the best or most used in the future, that is, in about 5-10 years. Take into account system administration and applications. This are the languages i had in mind, add more if you think other scripting languages are better or worth considering.

I need to find a way to download the attachment from a daily report e-mail to me. The kicker is it will need to be down with a cron tabbed bash script.For example, which linux based CLI client is best suited to be scripted?

I'm trying to put together a script that will quickly run through an archive directory of log files that are named by day of the month 01.gz, 02.gz, 03.gz.... 31.gz. The script uses gunzip -c | grep | wc to count up the total number of hourly occurrences of a filename and outputs the results to stdout.
The only snag I have left is the octal limit when it gets to 08 and 09. I've seen examples using perl and awk, but this script uses a number of nested for loops and if statements that I don't want to have to rewrite in a different syntax. I found that I can use num=10#08 to set that variable to a base 10 instead of a base 8, but then I lose the leading 0 again when it passes the number to the next filename variable.

I am a newbie, I am writing a script file to execute some programs.
# ! bin/ bash
clear
echo "*************************************"
echo " ACOUSTIC MODELLING - BELLHOP "
echo "*************************************"
#exec ssh automatix
code....
problem 1 : I can ssh to the required space but after the terminal prompts me for password it stops ececuting the script.
problem 2: after performing the 'exec' command for the first time. its not executing anything after that line. is there any work around for this.

We have to (re)write a bunch of scripts to download files from remote ftp servers, where we won't know the names beforehand; move the files to an archive folder on the FTP server; copy the files to the correct servers on our LAN; and log the file information in Oracle.Our current scripts are for a windows product called ScriptFTP that provides a nice little language. It does everything except the logging, but we're wanting to get rid of Windows.
I have recently been given the job of maintaining the code, and I'm looking for a good language for simple, robust ftp scripts that will work on Linux. We have some customers with remarkably unreliable FTP servers. If necessary, I can write another program to handle the logging to Oracle. I'm usually a C++ developer, so a similar syntax is a bonus. I also want to be able to hand this over to an entry-level programmer later.
So far, I'm intrigued by PHP, but I've hardly had a chance to look at it for any scripting. I like the idea of being able to loop through the files individually and even be able to skip over anything that looks like it's currently being written (either based on the file name or date/time). I've thought about writing something in C++ that would take a simple config file instead of a full blown script. However, I don't want the maintenance, unless someone writes a quality FTP library that is inexpensive (hopefully free) for commercial use.

I am going to school for Network Engineering and hope to one day be a systems administrator or something similar. I was wondering what some good scripting languages would be to learn. I know the obvious, Python, Perl, Shell Scripting and PHP, but what else?

I am familiar with C, C++, and Python at a novice level. I have recently tried learning bash, but I can't seem to wrap my head around it. My biggest problem, I think, is the huge "vocabulary"-- it seems like there are thousands of commonly used commands, and several ways to use said commands.I've done some google searches but can't seem to find scripting tutorials that tailor to n00bs. Most go from basic "Hello World" programs to very complex scripts.

am working an a worksheet where I need to lookup id in an other worksheet.The script works as long as I am staying on the same row. When pressing key up or enter the corresponmding lookup information is not placed on the very same row.In short terms, I want the lookup data to be enterd on the same row no matter what key I am pressing.
The script:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim cfind As Range
On Error Resume Next
If Intersect(Target, Range("A:A")) Is Nothing Then Exit Sub
thisRow = ActiveCell.Row
[code].....
This example is set to Enter key procedure. So when the enter key is pressed, my current row will change by 1 so I have to compensate for that. All I want is that the data will be correctly enterd no matter what key I am pressing.

You are probably using systemd (check it with ps --pid 1) and therefore /etc/init.d isn't considered for autostart. Here can you find some information about systemd and autostart [1]. As far as I know systemd isn't intended to start applications with systemd. I recommend you to use the autostart feature of your window manager or desktop environment or at least the .xinitrc.

I've been using Ubuntu for about 6 months now, but haven't had a need to start scripting until just recently. I know programming basics, but that's about it.Anyway, I have a program that I would normally run in this manner (note that I didn't create a permanent alias because I've been moving the program around a lot):alias dx='python /path/to/dxProgram.py' dx A_input.dx B_input.dxSo, you see, program dx takes two input files, and 'A' must come before 'B'. I have a folder full of these types of files that I'd like to loop through with this program. They're named as follows:
0_A_input.dx
0_B_input.dx
1_A_input.dx
[code]....

Does anyone have an example of a way to use ImageMagick or GIMP to Auto-White-Balance and scale 50% as a shell script? I'm asking because I usually do this to post-process photos in GIMP but being able to do this in a shell script means I could put it in Thunar in Xfce and save myself quite a bit of time.I checked the man page of mogrify and convert and didn't see any auto-white-balance type options that I am aware of

I need to write a bash script that will allow me to manage my "virtual network" (in reality just a bunch of directories and files). I need to obtain something like : I have my own command 'connect'. We can use it in two different modes: user and admin. If I type 'connect adashiu virtual_machine_name, computer will ask about password, if password is correct he will change a prompt to :
adashiu_at_virtual_machine_name >
after that user can start to use commands reserved only for user mode. Analogically with admin mode: prompt 'admin >' and administrator can only use bunch of commands reserved for him. changing prompt and separated commands for user and admin ?

I've got a situation. I'm having GNU bash version 3.00.16(1) on Solaris 10. I need to declare an array say arr1 which will be populated by an output of a command.
declare -a arr1
arr1=( $(/some/command) )
Supposing it will eventually (after executing the command) have element values as -
arr1[0]=1234
arr1[1]=5678
arr1[2]=7890
Now, I need to declare another set of arrays, one for each of the element values above - e.g.
declare -a arr1_1234
declare -a arr1_5678
declare -a arr1_7890
And I also need to populate elements of each of above 3 arrays with output of another command in a loop. So, these arrays will hold values something like -
arr1_1234[0]="abc"
arr1_1234[1]="def"
arr1_1234[2]="ghi"
arr1_5678[0]="jkl"
arr1_5678[1]="mno"
arr1_5678[2]="pqr"
arr1_7890[0]="tuv"
arr1_7890[1]="xyz"
arr1_7890[2]="aab"
I'm able to declare and populate arr1[*]. My question is how do I declare, populate and print the subsequent arrays and their elements?I am feeling rather thick to get this working.

I have wrote a 1 line command that parses a file, locates the IP Address in the file and then trims the output the way I want it, and then sorts numerically and by uniqueness and then >> appends to output.txt
I can get all the IP's into 1 file "output.txt", but what I am really looking for is some type of way to create a text file, for each IP it finds labeled xxx.xxx.xxx.xxx.txt and also put that ip address into that file..
xxx.xxx.xxx.xxx = the ip address it finds

I need to be able to compare a file date with system date and delete files older than 30 days.
the file name is basically
error_log.03222011
of course the extension is the date the file was created.
Oh and before i get hammered I looked everywhere but am unable to make sense of what I found.

I want to compare the following two tab-delimited .txt files (both were subsets of the original files) by comparing Columns 3 and 4 simultaneously. It is easy to compare C3 because both C3s are just numbers. But how to compare C4s?Basically, in File1, "G,G" = G in File2, "C,C" = C in File2, "A,A" = A in File2, "T,T"= T in File2.In File2, A/T in Column4 just equals "A,T" or "T,A" in Column4 of File1. C/T in Column4 just equals "C,T" or "T,C" in Column4 of File1, and etc.
File1:
C1C2 C3C4
ih509rs12345467244750"G,G"
ih499rs6049687244911"C,C"
ih508- 7244977"A,A"
