Also, like I mentioned earlier. I'm very new to this. How did your code fix my issue?
Expanding on what Scrutinizer said...
When the wc utility is given one or more operands, it reads from the named file(s) and prints the number of complete lines in each file and the file's name(s). (If more than one operand is given, it also prints a total line at the end.)
When no operands are given, wc reads from standard input and only prints the number of complete lines it found.
If you don't mind reversing the order (# of lines before file name) and you don't mind the total line at the end, this should be much more efficient:
This User Gave Thanks to Don Cragun For This Post:
1. Is there a way to count the number of bytes of a variable?
example:
abc@yahoo.com is 13 bytes
2. Cut command only allows one byte for delimiter
example: cut -f1 -d'.'
delimited by period. Is there a way to have two or more characters in the delimiter field?
thanks in adavance.

Hi All,
Is there is a way to do this in a single unix command
I have unzipped some files into a directory ..
I want to check the count of the files in the directory and also i need to check whether the files is having read permision or not.. I know it can be done by a script isthere... (4 Replies)
Hi All,
I'm trying to count how many line in my *.txt file.
My *.txt file has 1937 lines.
The problem is : when I use wc -l command
the result is 1936.
Again, I did some test. I create a new file with 100 lines with text editor (Notepad ++, Ultra edit).
And when I count it again with wc... (2 Replies)
Hi,
I have a script which removes 2 header records and 1 trailer record in a list of files. The commands doing the actions are
sed '1,2d' $file > tempfile1.dat
sed '$d' < tempfile1.dat > $output.txt
Its working fine for all records except a file having size=1445509814 and number of... (2 Replies)
I have created a file "pat".This file contains the text "abcdefghi". Now i want to count the characters in this file "pat". I gave wc -c | pat and it returns me exact count "9". Now when i tried like "echo pat | wc -m" It returns '4'. as for as i understand this command "echo pat | wc -m" should... (7 Replies)
Hi,
I have small query and a understanding, could you please clarify the query and correct my understanding..?
I am very big log file If i need to take a count and contained lines for a particular pattern/word i am using the grep command twice like the below.

I have a file that I need to count the number of "Y"s in the file, but just the "Y"s that fall between certain columns. Like:
file1:
1234567890123456789012345
BBBBBBYBBBBYBBYBBYBBYBBB
I want to count the 'Y's between 17 and 21 = 2 "Y"s

Hi all,
I need to run a bunch of commands seperated by ; but then count the total lines of output. Pipes and redirection don't seem to be helping me. Anyone know how I can do this properly:

Hello Experts,
I have a log file that contains 4 different type of exception :
1- Exception
2- Fatal
3- Error
4- Exec
My requirement is to find count of each type of exception, i tried using combination of -E and -C but that doesn't seems to be working :
grep -ec 'Exception' -ec... (4 Replies)

total
TOTAL(1) General Commands Manual TOTAL(1)NAME
total - sum up columns
SYNOPSIS
total [ -m ][ -sE | -p | -u | -l ][ -i{f|d}[N] ][ -o{f|d} ][ -tC ][ -N [ -r ]] [ file .. ]
DESCRIPTION
Total sums up columns of real numbers from one or more files and prints out the result on its standard output.
By default, total computes the straigt sum of each input column, but multiplication can be specified instead with the -p option. Likewise,
the -u option means find the upper limit (maximum), and -l means find the lower limit (minimum).
Sums of powers can be computed by giving an exponent with the -s option. (Note that there is no space between the -s and the exponent.)
This exponent can be any real number, positive or negative. The absolute value of the input is always taken before the power is computed
in order to avoid complex results. Thus, -s1 will produce a sum of absolute values. The default power (zero) is interpreted as a straight
sum without taking absolute values.
The -m option can be used to compute the mean rather than the total. For sums, the arithmetic mean is computed. For products, the geomet-
ric mean is computed. (A logarithmic sum of absolute values is used to avoid overflow, and zero values are silently ignored.)
If the input data is binary, the -id or -if option may be given for 64-bit double or 32-bit float values, respectively. Either option may
be followed immediately by an optional count, which defaults to 1, indicating the number of double or float binary values to read per
record on the input file. (There can be no space between the option and this count.) Similarly, the -od and -of options specify binary
double or float output, respectively. These options do not need a count, as this will be determined by the number of input channels.
A count can be given as the number of lines to read before computing a result. Normally, total reads each file to its end before producing
its result, but this behavior may be overridden by inserting blank lines in the input. For each blank input line, total produces a result
as if the end-of-file had been reached. If two blank lines immediately follow each other, total closes the file and proceeds to the next
one (after reporting the result). The -N option (where N is a decimal integer) tells total to produce a result and reset the calculation
after every N input lines. In addition, the -r option can be specified to override reinitialization and thus give a running total every N
lines (or every blank line). If the end of file is reached, the current total is printed and the calculation is reset before the next file
(with or without the -r option).
The -tC option can be used to specify the input and output tab character. The default tab character is TAB.
If no files are given, the standard input is read.
EXAMPLE
To compute the RMS value of colon-separated columns in a file:
total -t: -m -s2 input
To produce a running product of values from a file:
total -p -1 -r input
BUGS
If the input files have varying numbers of columns, mean values will certainly be off. Total will ignore missing column entries if the tab
separator is a non-white character, but cannot tell where a missing column should have been if the tab character is white.
