Server :: Gawk Works From Command Line But Not From Cron
Jun 5, 2010I have a very simple gawk script to add commas to numbers to make them more readable:
It works perfectly from the command line, but when run from cron it doesn't add the commas.

Server :: Crontab Fails But Command Line Works ?
Feb 19, 2011Having an odd problem running a mysqldump via crontab. I have the script running on other servers and they work fine, so not sure how to actually troubleshoot, but the script looks like the following;
If I run it as a cronjob as root, it finishes in a second and a 20k file is there. If I run it from the command line as root it does the backup (takes a few minutes) but does complete the backup and can be unzipped and read successfully.

General :: Difference Between Cron And Command Line Environment?
Feb 18, 2010so i have a few shell scripts that execute wonderfully when i type them at the command line but they fail when they are run from cron.
for example, if i run a script from command line that contains
Code:
shopt -s nullglob
to prevent problems with for f in *.mp4 type loops, it works fine from terminal command line but when called from cron, it gives an error->
Code:
/home/centralsqwall/Videos/videochecker.sh: 91: shopt: not found
a couple other random errors as well...
so there is some difference in the shell from cron and the terminal?
i'm running ubuntu 9.10, #!/bin/bash
what are the commands i should be using to echo my environment or simulate cron environment from the terminal?

Programming :: Gawk Getline Eats Next Line For Processing?
Mar 19, 2011I'm working on a simple data processing script.My script uses a loop with getline to check for the value on the next line to decide if it's time to terminate the loop.This works dandy, but the problem is that getline eats that line, which then isn't processed by the rules in the remainder of the script (even though I want it to be). To illustrate what I mean, consider this simple gawk script:

Ubuntu Networking :: Ad-Hoc Works With GUI But Not Command Line
Jul 17, 2010I have two Roboards that need to communicate with one another. I have sucessfully installed Ubuntu 9.04 using the 386 kernel based on instructions found online.I can use the GUI to set up an Ad-Hoc network using one Roboard ("Create New Wireless Network"), call it Manet, and connect to "Manet" using the GUI on the other Roboard and ping/ssh between the boards. However, when I try to create the same wireless network using the command line using:
ifconfig wlan2 down
iwconfig wlan2 key off essid 'Manet' channel 5 ap any
ifconfig wlan2 up
I don't see any entry in iwconfig under "Cell". It keeps giving me "Not Associated"When I try to enter the same information on the other Roboard to try to connect to the network, it doesn't connect and under iwconfig, I don't even see any entry for ESSID. Could somebody please tell me why it works when I use the GUI and not the command line.

Software :: Command Line Browsing That Works With JavaScript Sites?
May 9, 2011How can I verify JavaScript on a site (not on the same server) is working from command line access of the URL?
On checking some of what was written in 2005 I find most of it isn't still relevant (if it was then - I noted the w3m-js stuff mentioned in 2005 hadn't been updated since 2003).
Since then a couple of times I've looked into it but didn't make much headway but also didn't spend a lot of time on it. So far as I could tell from other posts I'd seen others hadn't either.
Recently I found out about Mozilla's SpiderMoneky js library and that it could be linked into elinks text browser and did same on my RHEL5 system.
I found Spidermonkey rpms in the EPEL (Fedora sponsored) repository:
js-1.70-8.el5.i386.rpm
js-1.70-8.el5.x86_64.rpm
js-devel-1.70-8.el5.i386.rpm
js-devel-1.70-8.el5.x86_64.rpm
I was able to download and install using rpm then compile elinks from source to include the above. Running elinks version after that shows the ECMAScript support is compiled into the new elinks binary. Also setting various ecmas* flags in the elinks.conf does have effect so clearly it is using them. (As opposed to another system where I use the original RHEL5 provided elinks RPM it complains about the ecmas* stuff being invalid options.)
It appears that by default it has this enabled but just for good measure I added:
set ecmascript.enable = 1.
Despite that when I pull up the page I see:
This product requires use of a browser that supports JavaScript
As a test I set the above to 0 on the off chance it was backwards and saw the same thing.
I then set the following:
set ecmascript.error_reporting = 1
On pulling up the page I now see a popup box:
Quote:
JavaScript Error:
A script embedded in the current document raised the
following exception:
TypeError: Window.Focus is not a function
OK
That seems to suggest that despite the earlier message about needing a browser that supports JavaScript that it is in fact executing at least one JS but that it is getting an error. Can anyone confirm that?
Does anyone have any idea what I�d need to do to deal with the Window.Focus message?
Essentially the site is a login page and even though I am able to input username and password after opening in browser when I tell it to POST it simply returns to the same login/password page.
And of course it doesn't have to be elinks/spidermonkey. I'd be interested in finding out if anyone knows a way I can verify a site that is running JavaScript is actually responding properly from command line rather than via a browser?
The SpiderMonkey stuff from Mozilla when compiled into elinks is supposed to do that but given my results Im not sure if it is or not.
Most of the documentation I can find on JavaScript stuff appears to be aimed at developers testing their own JS code from command line rather than accessing a web page with JavaScript.
Programming :: BASH - Works On The Command Line, Hangs As A Script?
Jul 16, 2010I'm writing a Bash script to take IPTC keywords from a text file and write them, via Exiv2, to several (first batch is 100) JPEG files in a single directory. The script has one while loop inside another while loop, both terminated, but I'm pretty sure that's not my problem. I think it's how I'm incrementing the "counter" variable, although it could also be the method of parsing the text lines from the file (using cut with delimiters that have worked fine in simpler scripts).
Here's the code as I've worked it up to this point.
Code:
And yes, "keywords" checks out in Crimson Editor, Emacs GUI and nano as an ASCII file with UNIX line endings. No issues on that score.
Feeding each line consecutively into a terminal (excepting the exiv2 command) works fine: each variable echoes with the part of the text line used as a variable value as it should, even when the b variable is incremented the quick&dirty way (up arrow three commands and hit enter).
Running the above script in eval mode (sh -x) stalls after setting the b variable to one and reading in the first line of text. I'd like to know why. I'd also like some advice on another reliable method of parsing the read-in lines.

General :: CIFS Mounting Works Via Command Line - Fails With Fstab
Dec 2, 2009I've successfully mounted a network share with mount.cifs for the past 2 years using fstab with credfile.
[Code]....
Yesterday I moved this system to a new datacenter, but did not alter fstab or the credfile. The //server/share directory has IP rules in place, but this was updated with the new system IP while we moved the system. Now, I am mysteriously unable to automount //server/share. The local error is 13 (permission denied). The Windows server we are mounting returned a code that is defined as "username is valid but password is incorrect" Again - no changes (content or permissions) were made to my credfile or fstab entry. I've restarted netfs a few times, including rebooting the system twice. What is baffling is I can successfully mount //server/share via command line: Code: mount -t cifs //server/share /mnt/mycooldir -o username=foobar,password=1234
The username and passwords are identical in credfile and the mount options - I copied & pasted username / password from the credfile itself.
Programming :: Command Line Works - Won't Work From Inside Bash Script
Feb 16, 2011Writing script to create backup of file by adding datetime to file name. Basically test for file presence if there, cp with datetime then rm original cp works fine from command line but get cannot stat `full path to file': No such file or directory
Code:
Here are the errors: cp: cannot stat `~/html/CVP_dadamail/.dada_files/.logs/errors.txt': No such file or directory rm: cannot remove `...': No such file or directory
The for statement is a placeholder as I have same file to backup out of several directories. using "bash -x scriptname" -OR- inserting echos, I can see I've constructed the strings properly. Believing it might be related to the hidden directories, I tried setting the shopt "glob" options to no avail.
Ultimately I'll add the other directories to the for loop and then run this from a cron job, so if you see potential pitfalls knowing I'm headed in that direction...believe construct would be

General :: ImageMagick's "import" Command Line Program Failing To Take A Screenshot From CRON Script
Feb 16, 2011I wrote a simple command line script which is suppose to take my screenshot every 5 minutes.(using ImageMagick's "import" program)
Here is the script (shottr.sh):
This is working fine if I execute by hand i.e:
The script itself is being executed (I hear a voice saying: "Screenshot") but the actual screenshot is not taken.
Be assured that it is NOT permission issue (I placed a simple "touch" invocation and file was created)
May be if it's run from cron...it doesn't have a "window" so it can't take a screenshot from nowhere? If that is the case, then how can I workaround it?

Jan 4, 2010I want my server to automatically shutdown at 23:59 and startup at 8:00. The startup is handled through by bios but the shutdown is to be managed through cron. I thought I had this working, I actually swear I had it working because I thought the uptime command showed the appropriate uptime. I happened to be up and was streaming a movie from my server when at the time it should've shutdown it actually just restarted. If I run the shutdown -h now command by itself it works well but the scheduled command just restarts the server. Here is the what is shown when I enter crontab -e.

Jun 30, 2010Whilst I have used GUI-based Linux distros for the last few years, I am now struggling somewhat when it comes to setting up a server from the command line. All the howto's I've read so far tell you how to set up certain things, but I don't know what I actually need to set up.Rather than asking the same questions all over again on a forum like this, and generally being a bit of a noob, I wonder if there's a resource somewhere that someone could direct me to in order to know what I need to do to set up a fileserver.
The hardware is all done, and I will probably set up a router distro like IpCop to manage the network, but I'm rather lost as to what packages I need, and how to know what the server is/isn't doing.I've used plenty of command lines in the past (ms dos, amiga dos, BASIC programming etc), just not a linux command line. All I've ever done is mount a few drives, use nmap and started x
CentOS 5 Server :: Setting Up CUPS (command Line) On New Server?
Mar 29, 2009I was using Red Hat 7.3 forever and decided it was time for a change. I went to Fedora 10 but it was really buggy. CentOS 5.2 is VERY stable.Here is my problem.The server is command line only -- I tend to hate GUI"S.I setup Samba no problem disabling the ports needed through the firewall and that was straightforward.CUPS is a nightmare for me since CentOS locks down the cupsd.conf and then the firewall does its thing. I allowed port 631 through the firewall but then got lost on the cupsd.conf. It's been too long and the old redhat one won't work with CentOS (not surprising since it's a VERY old system) straight-forward CUPS tutorial for a command line interface. I just need it to be:

b) do that

When I test it on the command line everything works but when I run it in cron the jpg file pops up but the beep doesn't beep. I'm thinking the problem is in the "echo -e \a" part.
