Hi Foamers
I have a question about log and | tee log in OpenFOAM.
If I interrupt a run in OpenFOAM for example at t=10sec and then continue it some time later; all the data that was previously been written in the log file (here from t=0 to t=10 sec) will be replaced by this new values (t=10 afterward).
So is it possible to use this | tee log in OpenFOAM to write these new data at the end of the previous log file instead of deleting and replacing the old data?

Greetings Mohsen,

Did you try checking the help provided by the tee command?

tee --help

Or:

man tee

Best regards,
Bruno

Thanks Bruno for the quick answer.
yeah it was very simple. I think I should turn off my PC and get some sleep!

tee log --help
Usage: tee [OPTION]... [FILE]...
Copy standard input to each FILE, and also to standard output.

  -a, --append              append to the given FILEs, do not overwrite
  -i, --ignore-interrupts   ignore interrupt signals
      --help     display this help and exit
      --version  output version information and exit

If a FILE is -, copy again to standard output.

Report tee bugs to bug-coreutils@gnu.org
GNU coreutils home page: <http://www.gnu.org/software/coreutils/>
General help using GNU software: <http://www.gnu.org/gethelp/>
For complete documentation, run: info coreutils 'tee invocation'

and

 | tee log -a

worked for me.

Thanks

By the way, How can I exit from the Manual using:

man tee

and go to the next line in the Terminal without closing it?

It should be written at the end of the terminal:

Manual page tee(1) line 4/49 (END) (press h for help or q to quit)

Thanks Bruno

Considering tee is a command that enables output to be written to both standard output and files, some may want to generate separate log files. In that case, I append the files, one to another:

cat log* >> log_all
