how efficient is it, and how practical is it to call outside programs in a shell script (bash) for small tasks?
for example, say i have a script that might preform many tasks, one of those tasks may require root access; rather than implementing inside the script a method to use su or sudo to... (11 Replies)
Hi

The code is that:

Hello Everyone!
I am a newbie. I'd like to get key lines from a big txt file by Reg Exp, The file is nearly 22MB.
GREP or SED?which may be the best choice,more efficient way?
or any other best practise?
Thank you in advance.

I have the following awk one-liner I came up with last night to gather some data. and it works pretty well (apologies, I'm quite new with awk, and don't know how to format this pretty-printed). You can see the output with it.

I've got this program set up so that it creates files whose unique names specify the jobs their contents describe. In order to retrieve the information inside those files, I have to do a "grep" and awk or sed to extract it. I've just assumed that making a directory with that unique name that... (1 Reply)
I have a very inefficient awk below that I need some help improving. Basically, there are three parts, that ideally, could be combined into one search and one output file. Thank you :).

DESCRIPTION
Each of these functions finds the first element with the minimum magnitude in a complex vector, then puts the real and imaginary parts of
it into min[0] and min[1], respectively.
PARAMETERS
Each of the functions takes the following arguments:
min Pointer to the first element with the minimum magnitude.
x Pointer to the first element of the source vector.
n Number of elements in the source vector.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
