Here change ' NR>3' according to the number of lines for columns headings
Hope this piece of code is useful to you.
Thanks I got it to work just had one trouble and that was the variable $recount ended up having a carriage return in it so the compare kept failing. I ended up writing it to a file then using the file results. I am not sure if there is a better or easier way but here is what I did.
i have a file named file_names.dat where there are several files along with their path.
exp:
/data1/dir1/CTA_ACD_20071208.dat
/data1/dir1/CTA_DFG_20071208.dat
i want to write a script which will create a csv file with the name of the file and record count of that file
the output file... (4 Replies)
i use unix command to take the record count for a file1
awk 'END{print NR}' filename
i already have a file2 which conatin the count like
...
..
rec_cnt=100

I want to replace the record in the file2 using the record i take from file1.
suggest me some simple ways of doing it... (2 Replies)
Hi all
How to verify the number of records in case of delimited file, If the file has records. And then if it is not equal to mentioned no. of records, email is triggered and file is moved to bad directory path.
Example

input file = a.txt
bad directory path : /usr/bin/bad (6 Replies)

We have the below records where we need record count of every 30 minute like 00:01 to 00:30 so in that we will have 48 record count in 24 hrs , and also we need sum of record count from 00:01 to 23:30. Please find sample data as well.

unbuffer
UNBUFFER(1) General Commands Manual UNBUFFER(1)NAME
unbuffer - unbuffer output
SYNOPSIS
unbuffer program [ args ]
INTRODUCTION
unbuffer disables the output buffering that occurs when program output is redirected from non-interactive programs. For example, suppose
you are watching the output from a fifo by running it through od and then more.
od -c /tmp/fifo | more
You will not see anything until a full page of output has been produced.
You can disable this automatic buffering as follows:
unbuffer od -c /tmp/fifo | more
Normally, unbuffer does not read from stdin. This simplifies use of unbuffer in some situations. To use unbuffer in a pipeline, use the
-p flag. Example:
process1 | unbuffer -p process2 | process3
CAVEATS
unbuffer -p may appear to work incorrectly if a process feeding input to unbuffer exits. Consider:
process1 | unbuffer -p process2 | process3
If process1 exits, process2 may not yet have finished. It is impossible for unbuffer to know long to wait for process2 and process2 may
not ever finish, for example, if it is a filter. For expediency, unbuffer simply exits when it encounters an EOF from either its input or
process2.
In order to have a version of unbuffer that worked in all situations, an oracle would be necessary. If you want an application-specific
solution, workarounds or hand-coded Expect may be more suitable. For example, the following example shows how to allow grep to finish pro-
cessing when the cat before it finishes first. Using cat to feed grep would never require unbuffer in real life. It is merely a place-
holder for some imaginary process that may or may not finish. Similarly, the final cat at the end of the pipeline is also a placeholder
for another process.
$ cat /tmp/abcdef.log | grep abc | cat
abcdef
xxxabc defxxx
$ cat /tmp/abcdef.log | unbuffer grep abc | cat
$ (cat /tmp/abcdef.log ; sleep 1) | unbuffer grep abc | cat
abcdef
xxxabc defxxx
$
BUGS
The man page is longer than the program.
