To install fv on Ubuntu Linux system:
- Down load the appropriate tar file to your distribution from http://heasarc.gsfc.nasa.gov/docs/softw ... nload.html. The current fv tar file is "fv5.4_pc_linux64.tar.gz" for 64-bits Ubuntu Linux.
- Using the tar file above as an example, open the Terminal, move to the directory where the download is and then
- gunzip -c fv5.4_pc_linux64.tar.gz | tar xf - #Unpack the gzipped file. The general rule is "gunzip -c fv5.4_<ARCH>.tar.gz | tar xf -", where <ARCH> depends on the downloaded file
- cd fv5.4/ #Move to the extracted directory
- ./fv #Launch and run fv
