Need help please with Grep/Sed command to extract text and numbers from a file
Hello All,
I need to extract lines from a file that contains ALPHANUMERIC and the length of Alphanumeric is set to 16. I have pasted the sample of the lines from the text file that I have created.
My problem is that sometimes 16 appears in other part of the line. I'm only interested to print lines that contain 16 which comes after ALPHANUMERIC
Basically the 16 is the lentgh of ALPHANUMERIC Charcters.
In the first line for example ALPHANUMERIC 16 << I need to print
lines that contain ALPHANUMERIC and that it is set t o16
Can u please help??? I tried many grep command but cannot get this working. I do not know perl and never worked with sed

I'd like to copy strings from a log file and put them into a CSV.
The strings could be on different line numbers, depending on size of log.
Example Log File:
File = foo.bat
Date = 11/11/11
User = Foo Bar
Size = 1024
...
CSV should look like:
"foo.bat","11/11/11","Foo Bar","1024" (7 Replies)

tail
TAIL(1) General Commands Manual TAIL(1)NAME
tail - deliver the last part of a file
SYNOPSIS
tail [ +-number[lbc][rf] ] [ file ]
tail [ -fr ] [ -n nlines ] [ -c ncharacters ] [ file ]
DESCRIPTION
Tail copies the named file to the standard output beginning at a designated place. If no file is named, the standard input is copied.
Copying begins at position +number measured from the beginning, or -number from the end of the input. Number is counted in lines, 1K
blocks or characters, according to the appended flag or Default is -10l (ten ell).
The further flag causes tail to print lines from the end of the file in reverse order; (follow) causes tail, after printing to the end, to
keep watch and print further data as it appears.
The second syntax is that promulgated by POSIX, where the numbers rather than the options are signed.
EXAMPLES
tail file
Print the last 10 lines of a file.
tail +0f file
Print a file, and continue to watch data accumulate as it grows.
sed 10q file
Print the first 10 lines of a file.
SOURCE
/sys/src/cmd/tail.c
BUGS
Tails relative to the end of the file are treasured up in a buffer, and thus are limited in length.
According to custom, option +number counts lines from 1, and counts blocks and characters from 0.
