Errors running bash script files

bkdc · 01-31-2008, 03:47 PM

Here is a summary of my problem, following is a simple script & results.
Problem:
I am having a problem running even the most simple bash script file. I have tried everything that I could think of but nothing seems to correct the problem. My feeling that it may be something really stupid (I've been away from this stuff for several years & now trying to get back into it).
Linux distro is PCLinxOS 2007
Here is a sample script & the related problems. I have cut & pasted the command lines into a Konsole window & all works fine but running as a bash script is another story. PLEASE NOTE: That this scenario is true for any script I try, no just this one.
Script used for testing
#!/usr/bin/bash
# Disk Usaage test Script
# List directory contents
#
Dir=`pwd`
clear
echo "Current directory is $Dir \n"
echo "Disk Usage is as follows...\n"
echo "File by size 0....999999\n"
du -s *|sort -rnk 1,1

Test Results from attempt to run

: command not found
\nrent directory is /home/df10475
Disk Usage is as follows...\n
File by size 0....999999\n
sort: stray character in field spec: invalid field specification `1,1\r'
df10475@~ :$

Thing I have done:
- Verified /etc/passwd etc/profile $HOME/bash_profile PATH
- Tried running as ROOT (same results)
- Re-entered the script using vi instead of KWrite
- Re-installed bash

I am open to all suggestions & a second set of eyes.
I have only been using PCLOS for about 2 months & this is the first attempt at scripting using this distro.

Code:

#!/usr/bin/bash

Every distro I've used so far, bash is in /bin, not /usr/bin.
Change it to

Code:

#!/bin/bash

To verify where bash in in PCLOS, in a console window, enter 'which bash' (without quotes).

You might also try splitting up the du command line. Put the du -s * part at the end of the 'disk usage' line, and the sort -mk 1,1 part at the end of the 'file by size' line.

PS: I've got a working copy of the corrected code which still needs a minor tweak or two to format display. If you haven't solved it in a couple of days, show me what you've got. Then I'll show you mine.

No kinky thoughts from you perverts please.

bigrig makes a good point that you should keep in mind even if it doesn't fix your specific problem: /usr/bin is not the same as /bin. If it is, you've screwed something up horribly :-P. Something to keep in mind for your future scripting expeditions.

Happy Hunting :-)

lets make a simple script to test as non root

-------------copy and paste into editor------
#!/bin/bash
echo "I am not a pervert"
------------------------------------------

save the file in your home directory....I named it pervert

make it executable

Code:

chmod 700 pervert
ls -l pervert

output>>>>>-rwx------ 1 gordy gordy 38 2008-02-01 13:12 pervert*

run it....I have not added pathway = where ever to .bashrc so use the ./executable style

Code:

./pervert

output >>>>>I am not a pervert

har! har! har!

You are quite the comedian.

I like you sense of humor aus9.

Soon as I win the lottery, I'll book a trip to Austraila to meet you face to face and shake your hand.

Or perhaps drop one of those funnel-web beasties down your collar.

I haven't decided which yet.

Thanks for all the input

Good news for gankoji, I did not screw up however I did mess up a little.

BASH is in the correct directory, my brain was not...I know better but for some reason never gave it a thought. Once I made the change suggested by bigrigdriver everything appears to be working again, even the pervert script by aus9.

And community support comes through again. Pray tell, how much were your charged, either for the software, or the script support?
