Any files you transfer from Windows to Artemis HPC may be incompatible with Artemis due to differences in line endings between Windows and Linux. For example, if you submit a PBS script to Artemis that was created on Windows, it will submit normally, but it will fail with the following error:

-bash: /var/spool/PBS/mom_priv/jobs/1488497.pbsserver.SC: /bin/bash^M: bad interpreter: No such file or directory

The key here is the ^M character that appears in the error message, which indicates the file uses Windows line endings.

To fix this error, convert line endings from Windows format to an Artemis HPC compatible format by either:

• Running dos2unix on files transferred to Artemis HPC from Windows
• Saving files created on Windows in “Unix” format

Converting line endings using dos2unix

After copying files created on Windows to Artemis, run them through dos2unix:

[abcd1234@login4 ~]$ file input.txt
input.txt: ASCII English text, with CRLF line terminators

[abcd1234@login4 ~]$ dos2unix input.txt
dos2unix: converting file input.txt to UNIX format ...
[abcd1234@login4 ~]$ file input.txt
input.txt: ASCII English text

Converting line endings using Notepad++

Using Notepad++, you can request your file is saved with Artemis HPC compatible line endings. Click Edit -> EOL Conversion -> Unix (LF), then click Save. If you have followed this procedure, you can then copy this saved file to Artemis and it will be compatible.
