New page

*Accessing the cs lmu system:
my.cs.lmu.edu - in putty.exe
ssh username@my.cs.lmu.edu - in terminal
==Commands==
**''Exit''
**''pwd'' : "print working directory" - shows the path to your current directory
**''ls'' : "list files"
***blue- folders, white- documents
**''cd <name>'': "change directory"
*** <name> = .. allows you to go up one directory
**''cat <filename>'' : shows contents of a file
**''more <filename>'' : shows truncated file contents that allows you to page around
***space- page down
***b- page up
***q- quit truncated view
**''wc <filename>'' : word count of a file
***display: lines / words / characters
**''grep "searchterm" <filename>'' : search for text
***exclusively searchterm - " searchterm "
***searchterm at end of line - "searchterm$"
***searchterm at beginning of line - "^searchterm"
**''sed'' : replacing text
***"s/<searchtext>/<replacetext>/g" <filename>'' : one time search and replace (words)
***"y/<unqiuecharacters>/<newuniquecharacters>/" : letter by letter replacement
***sed "s/.../& /g" <filename> to group sequence into codons
****"..." any character
****"&" what you just found
==Putting Commands Together==
* vertical bar ( | ) used to link commands together
**ex. grep "King" movie_titles.txt | sed s/King/Queen/g
***not necessary to reiterate file name, as you want the first command to act ONLY on the text of the second

*Ways to access dondi's data folder
*#cd /nfs/home/dondi/xmlpipedb/data
*#cd ~dondi/xmlpipedb/data

		+	==Using XMLPipeDB Match==
		+	*Invoke with the command ''java -jar xmlpipedb-match-1.1.1.jar "<regex>"''
		+	**This is the basic command and will prompt a text input
		+	**The regex is the search term that XMLPipeDB, like grep, will find
		+	***Unlike grep, this program offers extra statistics (total # unique matches and a count breakdown without echo'ing lines)
		+	***The regex can be broadened to find various search terms
		+	****ex. "d.g" would identify any three character sequences beginning with d and ending with g
		+	****ex. "do[gbd]" identifies a more restrictd three character sequence
