Fedora 15 chapter 7 & 8

Linux Fedora 15
Chapter 7
1. The shell waits for the command to finish executing. You can send the command to the background by using "&".
2. cat list | sort | lpr
3. A PID number is an identification number assigned to a command running in the background, which can be used to differentiate between commands. The PS (process status) utility.
4. $ ls section*
$ ls section[1-3]
$ ls i*
$ ls*[13]
5. fgrep -i 'a' | wc -l fgrep 'a' find lines containing "a"; the -i option tells it to ignore the case (thus both "A" and "a")
You could also use the other *grep-commands, and you could specify both A and a (eg. "egrep '[Aa]') wc counts lines, words and characters; the -l option makes it just write number of lines. ls | fgrep '$(.' ls -S | lpr or ls -S > /dev/lpt (probably requires root-privileges)
(ls -S sorts by size - largest first. Other useful options: -r reverse current sorting. -s adds the size before filename. -l long listing. -t sort by creation time.)
6. $ sort numbers > phone_list
$ cat permdemos.c | tr '[{}]' '(())'
$ cat part[12] > book
7. cat and grep tr 8. $ grep \$Id id_list
$ grep -i suzi < addresses
$ grep -il memo *.txt > memoranda_files
$ file /usr/bin/* | grep "Again shell script" | sort -r
