在Linux下大量改變副檔名

雖然在linux之下副檔名並沒有什麼意義, 但是有時候為了辨識容易還是會用到.這裡提供一下在bash/C shell下如何大量改變副檔名

Bourne Shell:

for f in *.foo; do
 base=`basename $f .foo`
 mv $f $base.bar
done

C Shell:

foreach f ( *.foo )
 mv $f $f:r.bar
end

make your own ls color

o. add this three line to your ~/.bashrc

alias ls='ls --color'

LS_COLORS='di=1:fi=0:ln=31:pi=5:so=5:bd=5:cd=5:or=31:mi=0:ex=35:*.rpm=90'

export LS_COLORS

o. parameter meaning:

di = directory

fi = file

ln = symbolic link

pi = fifo file

so = socket file

bd = block (buffered) special file

cd = character (unbuffered) special file

or = symbolic link pointing to a non-existent file (orphan)

mi = non-existent file pointed to by a symbolic link (visible when you type ls -l)

ex = file which is executable (ie. has 'x' set in permissions).

o. color number:

0 = default color

1 = bold

4 = underlined

5 = flashing text

7 = reverse field

31 = red

32 = green

33 = orange

34 = blue

35 = purple

36 = cyan

37 = grey

40 = black background

41 = red background

42 = green background

43 = orange background

44 = blue background

45 = purple background

46 = cyan background

47 = grey background

90 = dark grey

91 = light red

92 = light green

93 = yellow

94 = light blue

95 = light purple

96 = turquoise

100 = dark grey background
