Using sed in for loop
I have a file MAT.txt which contains the following data:
mat1.txt
mat2.txt
.
.
.
.
mat100.txt

I want to remove the '.txt' from every line and have an output file with the following data:
mat1
mat2
.
.
.
.
mat100

I know this can be done with sed easily for each line, but I do not know how to use sed in a loop and have a script that does the editing from line 1 to line 100.

The following code works, but I need it in a loop:

sed -e '/mat1.txt/s//mat1/g' -e '/mat2.txt/s//mat2/g' ............... -e '/mat100.txt/s//mat100/g' MAT.txt > MAT1.txt

Can somebody help me out?

       --criteria=

		 Valid criteria are: unbalanced weaknt strongnt twont strongtwo weaktwo three twoclubs 4441  singlesuit  twosuits  partscore  game
		 slam game-invite slam-invite jumpshift jumpfit splinter bacon weird

       --probability=factor
		 Generate  hands matching the criteria with only the given probability. Factor is in the range 0 to 1. On each attempt to generate
		 a board it is rejected if it doesn't match the criteria with the given probability.  A factor of about  0.8  gives  roughly  half
		 matching boards
