[H-GEN] Converting csv file to tab delimited text file

[Kelvin Heng]

hi guys,
I am writing scripts using bash shell in cygwin. Right now, I have a set of 
raw data that is daily exported from a server into a csv format. My script 
can only process a Tab Delimited text file, so I have to open the file in 
excel and save it as Tab Delimited text file. Anyone has any alternative to 
automate this process? Please comments.

Thanks in advance. :p

Kelvin Heng
Have A Nice Day!
