[R] help for

[Elham -]

hi all, I am following 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. I can not understand the mean of "Open a new terminal window and type".
i am using command.$ ls data/*.CEL > data/phenodata.txt in R

this returns an error


$ ls data/*.CEL > data/phenodata.txt Error: unexpected '$' in "$"
what should I do now?
