Assignment #3 - Beginning UNIX exercises (part 2) -
due date: TBA
Same instructions as always.
A bit deeper into Linux
touch, echo, clear, logging, history
pwd - issue this command to find out where you are -- useful following 'cd dirname'
grep -- to look for a string within a file or group of files (A note on dictionaries: the '/' at the beginning of "/usr/share/dict/linux.words" allows that file to be referenced from within your own directory..)
greplings -- some of the work done in class Monday the 12th.
more cat -- cat file1 file2 > file3 Similar to (part of) what I did in class Friday, Feb. 2
clear -- clears the screen
Logging a session - Note: The process for using the current telnet client in the lab may vary.Here's a bit of work I did with the British National Corpus (from the same folks who put together the OED and a story). And here are some multilingual word frequency lists.
history n -- shows the last n commands you've used
$ history 5
1032 cut -d' ' -f1 $b|head
1033 cut -d' ' -f1 $b|grep o$|wc
1034 grep o' ' $b|head
1035 grep o' ' $b|wc
1036 history 5
here we use grep and wc to investigate the history file a bit (note the use of double piping).
more practice with grep
with sort and paste
