http://www.unix.com – Hi, I have multiple files in a directory. Each file will have a header.I have to check if any of the files has 0 rows other than the header then I have to delete the files. Here “ Empty file” in my case means a file has header information but no data. I have to delete such files. If the file count =1 then delete the files else cp the files from one location to another. #!/bin/bash cd filepath rc=`awk '{n++} END {print n}' file1.csv` if [ $rc -ne 1 ]; then `cp /file1.csv file1path/file2.csv` exit $rc else `rm -rf file1.csv` fi The above script is good for checking one file bu (HowTos)

Hi, I'd like to process multiple files. For example: file1.txt file2.txt file3.txt

Each file contains several lines of data.

In advance, I appreciate any help or tips. I apologize for not providing examples of scripts I have already tried, the reason is that I am new to programming and do not really no where to start. I think this is possible with awk, but do not know how to go about learning how to write the script that would do the trick (ie, which commands to read up on).

I have two files like this

file1

a b c

file2

0 1 2

I want to output

a,0 b,1 c,2

Appending the two files like this

row(n) of file1 +","+ row(n) file2 for every n, total n is same in both files

I want to know is there any utility in shell which can help me do this, I do not want to use java file read file write for this or any loops. Can it be done using awk?

I have a directory that contains several files, out of which some files are have an extra extension for example

Code: FILENAME|FILE1.dat NO OF RECORDS|3 CHECKSUM|75.99 Could you please help me to write a shell script to compare 1. TOTAL RECORDS from FILE1.dat with NO of RECORDS in FILE.CTL 2.

I have two files.

I have been using awk to sum up multiple files, this is used to sum up the summary of server log parsing values, it really does speed up the final overall count but I have hit a minor problem and the typical examples I have hit on the web have not helped.

Here is the example:

cat file1 aa 1 bb 2 cc 3 ee 4

cat file2 aa 1 bb 2 cc 3 dd 4

cat file3 aa 1 bb 2 cc 3 ff 4

And the script:

cat test.

I have created a script which creates two files and reverses their contents if both the files are different.
