The UMobj suite of utilities provide command-line access to the UMIACS Object Store. UMobj is preinstalled on all UMIACS-supported Linux machines.
When to use UMobj
Use umobj if:
- you have a large number of files to upload (hundreds or thousands of files)
- you are uploading large files (files greater than 4GB in size)
Supported object storage clusters
We highly recommend setting a few environmental variables containing your credentials for convenience. When logged into the Object Store web interface (see list above), you can find these credentials on the user page. E.g. https://obj.umiacs.umd.edu/obj/user/
For example, if you use the bash shell, you can add something like the following to your .bashrc or .bash_profile.
export OBJ_ACCESS_KEY_ID="31sdfadDFAHFDN+344qOEIS" export OBJ_SECRET_ACCESS_KEY="NDSMK3233adfahadflkkPDSH092DSJKDKDJKFDLSFLNK" export OBJ_SERVER="obj.umiacs.umd.edu"
Or in tcsh you can do the following or add it into your .tcshrc.
setenv OBJ_ACCESS_KEY_ID "31sdfadDFAHFDN+344qOEIS" setenv OBJ_SECRET_ACCESS_KEY "NDSMK3233adfahadflkkPDSH092DSJKDKDJKFDLSFLNK" setenv OBJ_SERVER "obj.umiacs.umd.edu"
