  I have a tab-delimited file that has over 200 million lines. What's the fastest way in linux to convert this to a csv file? This file does have multiple lines of header information which I'll need to strip out down the road, but the number of lines of header is known.

• Is there any WinSCP equivalent for linux?

  - by MiniQuark

  I love WinSCP for Windows. What are the best equivalent softwares for linux? I tried to use sshfs to mount the remote file system on my local machine, but it is not as user friendly as simply launching a GUI, plus it seems to require root access on the client machine, which is not very convenient. Of course command line tools such as scp are possible, but I am looking for a simple GUI. Thanks!
