Tools

(You could read the "line", "shell", and "regular expression" parts later.)

~/bin

You could create a folder at anywhere (better if under your home directory) with any name you like (usually "bin") to create your own shell commands. After creating the folder, add this line to ~/.profile.local(create it if it doesn't exist) :

PATH=$PATH:~/bin

Then put your own scripts to the folder (~/bin here) and after logging out and re-logging in, you would be able to run any commands under the folder from anywhere.

# first -- sorry that in this case, you have to set the environment variables before running ./configure.
# the script will write "CFLAGS=xxx" in the generated Makefile, which is different from what I expected ("CFLAGS+=xxx").

# then run "make clean" in the four sub directorys and the topmost directory.

# do this before running ./configure --prefix=/full/path/to/the/target/directory
# notice that "./configure --prefix=$(workspace)/xxx" will not work.

# I know this is stupid, but it works...
