searching the first 10 characters of every line in a text file for a specific string, and if it was found, print out characters 11-20 of the line on which the string was found.
In this case, it's known that there... (13 Replies)

I need some help. I would like to read in a text file.
Take a variable such as ROW-D-01, compare it to what's in one line in the text file such as PROD/VM/ROW-D-01 and only input PROD/VM into a variable without the /ROW-D-01.
Is this possible? any help is appreciated. (2 Replies)

RANDOM(6) BSD Games Manual RANDOM(6)NAME
random -- random lines from a file or random numbers
SYNOPSIS
random [-elrUuw] [-f filename] [denominator]
DESCRIPTION
Random has two distinct modes of operations. The default is to read in lines from the standard input and randomly write them out to the
standard output with a probability of 1 / denominator. The default denominator for this mode of operation is 2, giving each line a 50/50
chance of being displayed.
The second mode of operation is to read in a file from filename and randomize the contents of the file and send it back out to standard out-
put. The contents can be randomized based off of newlines or based off of space characters as determined by isspace(3). The default
denominator for this mode of operation is 1, which gives each line a chance to be displayed, but in a random(3) order.
The options are as follows:
-e If the -e option is specified, random does not read or write anything, and simply exits with a random exit value of 0 to denominator
- 1, inclusive.
-f filename
The -f option is used to specify the filename to read from. Standard input is used if filename is set to '-'.
-l Randomize the input via newlines (the default).
-r The -r option guarantees that the output is unbuffered.
-U Tells random(6) that it is okay for it to reuse any given line or word when creating a randomized output.
-u Tells random(6) not to select the same line or word from a file more than once (the default). This does not guarantee uniqueness if
there are two of the same tokens from the input, but it does prevent selecting the same token more than once.
-w Randomize words separated by isspace(3) instead of newlines.
SEE ALSO random(3), fortune(6)HISTORY
The functionality to randomizing lines and words was added in 2003 by Sean Chittenden <seanc@FreeBSD.org>.
BUGS
No index is used when printing out tokens from the list which makes it rather slow for large files (10MB+). For smaller files, however, it
should still be quite fast and efficient.
