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)

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 :).

tau_get_event_vals
TAU_GET_EVENT_VALS(3) TAU Instrumentation API TAU_GET_EVENT_VALS(3)NAME
TAU_GET_EVENT_VALS - Gets user event data for given user events.
SYNOPSIS
C/C++:
TAU_GET_EVENT_VALS(const char **inUserEvents, int numUserEvents, int **numEvents, double **max, double **min, double **mean,
double **sumSqe);
DESCRIPTION
Retrieves user defined event data for the specified user defined events. The list of events are specified by the first parameter
(eventList) and the user specifies the number of events in the second parameter (numUserEvents). TAU returns the number of times the event
was invoked in the numUserEvents. The max, min, mean values are returned in the following parameters. TAU computes the sum of squares of
the given event and returns this value in the next argument (sumSqe).
EXAMPLE
C/C++ :
const char **eventList;
int numEvents;
TAU_GET_EVENT_NAMES(eventList, numEvents);
cout << "numEvents: " << numEvents << endl;
if (numEvents > 0) {
int *numSamples;
double *max;
double *min;
double *mean;
double *sumSqr;
TAU_GET_EVENT_VALS(eventList, numEvents, numSamples,
max, min, mean, sumSqr);
for (int i=0; i<numEvents; i++) {
cout << "-------------------
";
cout << "User Event: " << eventList[i] << endl;
cout << "Number of Samples: " << numSamples[i] << endl;
cout << "Maximum Value: " << max[i] << endl;
cout << "Minimum Value: " << min[i] << endl;
cout << "Mean Value: " << mean[i] << endl;
cout << "Sum Squared: " << sumSqr[i] << endl;
}
}
}
