If you omit the trailing slash or backslash characters, LSF treats the specification as a file name.
If the specified directory does not exist, LSF creates it on the execution host when it creates the standard error and standard output files.
By default, the output files have the following format:
Standard output: output_directory/job_ID.out
Standard error: error_directory/job_ID.err
bsub -o /usr/share/lsf_out/ myjob
bsub -e C:\lsf\work\lsf_err\\ myjob
