The explanations are in the IBM article; for example, 2 is about the “tar -C /path” syntax…

I don’t get the meaning in several, can you explain how to implement every one? Here are the ones that I understand

1 mkdir -p
2 ?
3 ?
4 Use doble quotes only when it´s really needed?
5 Mmmmh I understand use \n instead the enter itself, but why? what’s the difference?
6 Group… in a file and execute? or maybe use pipes?
7 Why use xargs instead find -exec
8 Detect when is usefull grep and when “grep -c”
9 awk ‘$2~/RegExp/’ instead grep “RegExp”
10 That’s classic stop using cat to pipe the output to another command

1. mkdir -p

3. echo “insert into bla (bla,bla) Values (bla,bla);|mysql && echo “select bla from bla;”|mysql

4. echo “$var” ?? in bash set vars with lowcase

5. echo -e “line 1\nline2\n”

6. ??? ls /usr/local/bin

7. deborphan|xargs apt-get remove –purge -y
