Programming :: Bash-shell-like Less Functionality In The Python Shell?
Jun 25, 2010Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.
Programming :: Three Scripts - Using Bash As Shell
Feb 9, 2010I am looking for three scripts (using bash as shell): to print out a list only with directories (no files) that they are found in running directory (no in subdirectories) to print out a list only with files (no directories) that they are bigger than 10Kb and are found in running directory (and in subdirectories) to print in the screen the lines of file with accidental order.

Programming :: Difference Between Formats In BASH Shell
Apr 30, 2009I searched around but I can't get a good handle on the difference between the following formats in BASH shell.
$VAR
$(VAR)
$((VAR))
$($VAR)
$(($VAR))
Can someone explain it, or point to a clear, concise document explaining it?
Programming :: Combining Commands And Var's In Bash Shell Script?
Jan 5, 2011I have a command which on the command line needs to look like this
rlam -if3 '!pvalue -H image1.jpg' > image2.jpg
Nevermind what rlam or pvalue do ... they are part of a program package I am using. The above command works on the command line, and also when written verbatim in a bash shell script.
My problem is: in the script I wish to replace image1.jpg with the content of a variable, e.g.
IM1=image1.jpg
How to I get the script to insert the value of $IM into the command when the pvalue part of it needs to be quoted?
Programming :: BASH Shell Differences: Login Or Interactive
Feb 18, 2011Intuitively I think that the Login Shell and the Interactive Shell are the same applications but have access to different environmental variables.It this true? Why is there more than one type of shell anyways? You can change users with the interactive shell, why not log on with it to?

Programming :: Creating Array From Command Output (Bash Shell Script)
Jan 26, 2011I have a command that outputs n lines of text, and I want to place each line into an array element, but I can't seem to get the syntax correct

Programming :: Perl About System Command / Fails If The Standard Shell Is Dash And Not Bash?
Jun 30, 2011I am trying to fix a perl script, and I really suck at perl. But I think this problem will be easy for people who know it.
The problem is, I have an old setup script someone wrote many years ago. It fails if the standard shell is dash and not bash. The only way I've gotten it to work is to point /bin/sh to bash. I looked thru the script and it uses "system" many places, and I think that's the problem.
I searched for it and found this link:url
My plan is to include this function:
Code:
sub system_bash {
my @args = ( "bash", "-c", shift );
system(@args);
}
Then I could simply change all calls to system into system_bash and it should work?
The parameter to the system calls is usually some variable. What if the parameter is a list already? Do I need to test for it somehow, and if it's a list, prepend "bash" and "-c" to the list? How do I do that?
In the script there are lots of places like this:
my $error = system($cmd);
if ($error) {
die/warn "some error message";
}
Shouldn't there be a return in the system_bash function?

How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

Programming :: Run Multiple Bash And Php Scripts From A Bash Script?
Jul 25, 2011I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?

Jan 9, 2010I would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.
