- That is really inconvenient and annoying. On one of the clusters I am using this "feature" does not allow me (in any practical terms) to see inverse.log for some minutes (after a dozen or more iterations). I can only use "tail" then, while I would prefer "less", but this is not the only my concern... > > I have tried to redirect stderr with "2>/dev/null" (for csg_inverse.sh), > > or putting "1>/dev/null 2>/dev/null" for inverse.gromacs.log tag, but the > > latter removes the logs altogether, which is not desired. > inverse.gromacs.log is a separate log file for gromacs program, but > not for csg_inverse itself, so that won't work here. > "Reading frame" goes to stderr, but forwarding that to /dev/null, one > would loss all other error messages. > You might be able to create a post-update script, which does something like: > sync && sed -e '/Reading frame/d' -i $CSGLOG - This could be a solution, if the performance of analysis tools was not affected, but writing so often to disk (after every single frame read!) should drastically increase the execution time during the reading stage, and it does take quite some time - about 20-30 mins for about 10 mln frames in trajectory in my latest case (which is relatively light in terms of the number of beads). - may I ask you what "exec 3>&1 4>&2 >> "$CSGLOG" 2>&1" does in enable_logging() (functions_common.sh)? I mean I could not find out the meaning of file descriptors "3" and "4" (I reckon exec redirects them).
