Running sed and counting number of lines processed

Hi all,

I have a tab-delimited text file of size 10Mb. I am trying to count the number of lines using,

Code: grep -c . sample.txt or

Code: wc -l < sample.txt or

Code: awk 'END {print NR}'  sample.txt All these commands shows the count as 1, which means they are reading only the first header line of the file.

Hi Everybody I want to write a script to count the number of lines in a file that don't ahve any thing on it, the free lines, i try to do it with fgrep "" which means to grep on the spaces but it does not work. help me please?

I try to count number of lines of a data.txt file and then if number of lines is greater than 1 then email me the file. I could not find what is wrong with my code, hope you can point out the mistake i made

Code: #!

Hi.I need to do a script that can receive any number of parameters which are file names and return the number of lines every file has.the output should be like that "The file nameoffile.txt has 5 lines".From what i have done my output is like "The file nameoffile.txt has 5 nameoffiletxt lines".how can I do the output without printing the name of file after the number of lines.

I know of course that

cat logfile.txt | wc -l 120

will tell me the number of lines in a file.

Whereas

tail -f logfile.txt

will show me the new lines that another program writes to logfile.txt.

Is it possible to combine both so that I get a continuous updating line count of logfile.txt with standard text utilities?

I do know about

watch wc -l logfile.txt

but I do not want to re-count th

I have a file with 22 lines. Each line has only 5 different chars, no white space, and each line is 3,278,824 in length.

i want to search a log for a string.

i want to search a log for occurrences of words and i want the result to tell me how many lines in the log contained each word.

if i type a command like this:

Code: egrep "cat|dog|monkey|bananas|bike" logfile i would like a response like this:

Code: cat=3,dog=17,monkey=1,bananas=102,bike=51 the numbers above for each word being searched for denotes the number of line

The following code will split the infile into multiple files. However, I need it to insert the same first 3 lines from the original input file into each splitted file. How do I modify my script below to do so:

Code: print -n "Enter file name to split?
