Adding a header to a log file
Hello,
I’m trying to add a row that will server as the header for a space separated file.
1-I have a number of files save in a directory
2- grep text path/*.log > newfile
newfile looks like this
Field1 Field2 Field3 Field4
Field1 Field2 Field3 Field4
Field1 Field2 Field3 Field4
Field1 Field2 Field3 Field4
This is fine as data is concerned.
However, I want to add or append newfile with a header (row1) so that it will look like this
Header1 Header2 Header3 Header4
Field1 Field2 Field3 Field4
Field1 Field2 Field3 Field4
Field1 Field2 Field3 Field4
Field1 Field2 Field3 Field4
Your help will be appreciated
