Hi Matt and Liam, Using '&' to fork Linux, provided some slightly different and interesting behavior, but I don't think it has solved the problem. typing $fsl& frees up the terminal for future use and launches the fsl GUI as well, but any commands typed after fsl& are not understood by BASH. I also tried having other shell tabs open in case the processes where diverted to other tabs. Here is an example: user@tux:~$ fsl& [1] 5648 user@tux:~$ fsl module avil& [2] 7528 user@tux:~$ module avil& [3] 8183 user@tux:~$ bash: module: command not found user@tux:~$ module load fslmaths& [1] 5661 user@tux:~$ fsl module load fsl-4.1& [1] 14158 I checked to see different terminal tabs but they were not giving output or recognising commands other than simple '$fsl&' or '$fsl' user@tux:~$ module load fslstats bash: module: command not found user@tux:~$ I installed FSL using apt-get. Perhaps apt-get configured and installed everything to an extent but fell short of setting up the local bash environment. I wonder if anyone knows how to set up BASH manually, so it recognises utility commands? Thanks for previous help or any future help. Russell. ------------------------------ Try fsl& Liam. ------------------------------ You don't need to type fsl to use the utilities. If you want to do this anyway, you can type fsl & which will send the fsl process to the background and allow you to continue typing commands. Peace, Matt. ------------------------------- Hello everyone, I am using FSL on Ubuntu Linux. I try to open fsl from the BASH prompt, not with the intention of using the GUI but to use utilities such as FSL maths and FSL statistics. However when I type fsl at the prompt the GUI automatically loads up, and the shell becomes useless (you can't type in further commands - like >load module etc). Does anyone know how to make it so that you can continue to type in commands after the GUI has loaded up in BASH on Linux? Any help is appreciated. Thanks. Russell. ------------------------------
