Hi Donna,
Thank you--this was very helpful! I am now able to extract the time of 
acquisition. 

Best wishes,
Sam

Hi Samantha,

You can't run that command by itself, because the grep command needs both a 
pattern and at least one file or standard input.  Greg's command below had a 
curl command followed by "|" to pipe the output of that command to the 
following grep command.  You could capture the output of the curl command to a 
log file, and then provide the log file as an argument to the grep command, if 
you have trouble running them all as one string, e.g.:

> curl -u username:password -X GET 
> ${host}/data/archive/projects/${project}/subjects/${subjectID}/experim
> ents/${session} > curl.${subjectID}.${session}.|og

> grep -e 'scans.*rfMRI\"' curl.${subjectID}.${session}.|og
