hi! I am following your link http://bioinformatics.knowledgeblog.org/2011/06/20/analysing-microarray-data-in-bioconductor/ I need to download phenotypic data in the form of text file that describe chip names, and the source of the biological samples as well as probe that hybridised to them. for that purpose i am using command.

$ ls data/*.CEL > data/phenodata.txt

this returns an error

$ ls data/*.CEL > data/phenodata.txt Error: unexpected '$' in "$"
