General :: Simple Bash Command Causing Bad Variable Name
Feb 18, 2010When I run this command from shell, it runs ok
export REVS=`svn info svn+ssh://svn.myone.ca/var/svn/story/trunk/lib |grep 'Last Changed Rev:'| awk -F: '{print $2}'`
However when I save it into a file called test.sh (of course, I chmod it with +x), I got error "export: 2: bad variable name"
Here is the file:
#!/bin/bash
export REVS=`svn info svn+ssh://svn.myone.ca/var/svn/story/trunk/lib |grep 'Last Changed Rev:'| awk -F: '{print $2}'`
I am using ubuntu.

Jul 9, 2011I wrote this script which works but it should run automatically about once per week. I hunted and experimented with KDE Task Scheduler (no dice and no help anywhere) and cron (confusing instructions and cannot edit crontab -e with vim, and cannot enter cron folders/files). I would settle for a desktop shortcut to run the script but found no for that.

General :: Executable File Apparently Doesn't Exist When Trying To Execute With Bash
May 9, 2011I downloaded a program called tonespace http://www.mucoder.net/en/tonespace/ which I extracted and then tried to execute the executable file with ./tonespace. This gives me the following message:
bash: ./tonespace: No such file or directory
When I use the command: file ./tonespace I get this: tonespace: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped
I dont get it. The file is clearly there, yet when trying to execute it bash doesn't seem to recognize it.
It has permissions rwxr-xr-x and is not owned by root. Am I overlooking something?

View 7 Replies View RelatedGeneral :: Unable To Execute The Setrcs
Jan 7, 2010I used to execute the command setrcs /data/dev/projects in a solaris machine. And all the files in the given path were visible from the current directory (whichever directory i am in). So that i need not copy necessary files required for compilation from the path to the current directory.
Ex: Suppose I am writing a C code x.c in the directory /root/test/. I do #include <bdm.c> in the file x.c. While executing I need not have the bdm.c in the current directory. Because I have executed the command setrcs /data/dev/projects. The compiler automatically looks for the bdm.c file in the path /data/dev/projects. But i am not able to execute the command setrcs in linux. Is there any similar command with similar functions or if there is any different command in Linux which serves my purpose.

Jun 16, 2010I've checked out a subversion project with source c++ files in netbeans 6.8 on Red Hat 5.5. My machine has a dual boot with windows xp and RHEL 5.5 so I checked out the project on a folder called winshare which is a shared drive/partition (E: under xp) allowing both operating systems to access the contents. I've Fedora as virtual machine on xp and wanted to be able to work on the source seamlessly whether using fedora or RHEL.
Problem is that Netbeans is able to build the source just fine but I can't seem to run the generated executable. It has -rw-rw---- permission and the owner is the same user logged in (let's say user1) but no matter what I do, whether I change permissions as user1 or root issuing command chmod 777 -R /dir/where/file/is does not have any effect whatsoever on the executable as well as any .cpp or .h files (nothing that I need exectue permissions on .cpp but just to make a point).

The script was saved to root's home directory and runs as part of root's crontab once a week. The script runs with no problem, but it doesn't actually seem to run all of the commands contained within. It skips some in the middle and the end and I don't know why. The script itself is this:

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:
Code:
server1 yes
server2 no
And in another server declaration data file, I got this datafile2:
Code:
server1=xxx1
server2=yyy1

Ubuntu :: Execute Bash Script After Running Process Finishes?
Jul 28, 2011I have a computation going which takes a long, but uncertain, amount of time. I have another computation which needs to be run, but _after_ the first one is done. I won't be at the computer at that time to manually start the new process. I've done some Googling, and I found how to delay execution by a specific amount of time (e.g. "start process x in exactly 8 minutes from now), but that isn't quite what I want to do. Essentially, I'd like to tell the shell, "When process #nnnn finishes running, then start process x". Is there a way to do this?
