UNIX : How to ignore lines with certain names

Sometimes we need to ignore multiple lines with certain words and get the list out of the file. usually it will be a log file to read .

UNIX : unpack and pack using tar

Tarball or tar is a utility in linux to unpack or pack the files. Lets say we have a file name hello.tar.gz which is packed and compressed. To unpack the file use the below command > tar xvzf hello.tar.gz This is unpack the compressed tarball file to the directory hello in current location. To pack a list of files to a compressed tarball file , we can follow the below steps. Let say we have the following list of files in Hello directory. > cd Hello > ls helloworld.py README.txt Move back to parent directory and give the below command. > cd .. > tar zcvf hello.tar.gz Hello This will create the compressed tar file in the current location
