Specifically what is the purpose of sed?
What is f?
Why is the 'cp f $phonefile' line needed when the script ‘goes live'?
Why might that two commands following sed be commented out at the present time ( i.e., during development)?

I am using this line of perl code to change the file format and remove ^M at the end of each line in files:
perl -i -pe's/\r$//;' <name of file here>
Can you explain to me what this code does, and translate it into bash/awk/sed? (2 Replies)
Hi,
I saw this. But I don't know why we need this?
ls mydir > foo.txt ## I know what this will do, it will take the results and write to the file called foo.txt
ls mydir > foo.txt 2>&1 ## Don't know why we need 2>&1
Thanks. (2 Replies)
Please explain grep -A 999999. I've seen this before, it always seems to be with six 9's as well. See an example below.

I have a requirement to remove all non-ascii characters from a fixed length file. I used the below command which is removing special characters but somehow the total record length is being truncated to one space less. If it is a multi-byte string then many characters at the end are being truncated.... (8 Replies)

time::localtime
Time::localtime(3pm) Perl Programmers Reference Guide Time::localtime(3pm)NAME
Time::localtime - by-name interface to Perl's built-in localtime() function
SYNOPSIS
use Time::localtime;
printf "Year is %d
", localtime->year() + 1900;
$now = ctime();
use Time::localtime;
use File::stat;
$date_string = ctime(stat($file)->mtime);
DESCRIPTION
This module's default exports override the core localtime() function, replacing it with a version that returns "Time::tm" objects. This
object has methods that return the similarly named structure field name from the C's tm structure from time.h; namely sec, min, hour, mday,
mon, year, wday, yday, and isdst.
You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that
this still overrides your core functions.) Access these fields as variables named with a preceding "tm_" in front their method names.
Thus, "$tm_obj->mday()" corresponds to $tm_mday if you import the fields.
The ctime() function provides a way of getting at the scalar sense of the original CORE::localtime() function.
To access this functionality without the core overrides, pass the "use" an empty import list, and then access function functions with their
full qualified names. On the other hand, the built-ins are still available via the "CORE::" pseudo-package.
NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
