How can I read file line by line

How can I read file line by line
I wont to read all lines and do same command to each line
for example if I have directory's paths like

./Load_spcl_cldspn_trn3_Jun_09_2007_153838.ch_log
./Load_spcl_cldspn_trn4_Jun_09_2007_153939.ch_log
./Load_spcl_cldspn_trn5_Jun_10_2007_071734.log
./Load_spcl_cldspn_trn4_Jun_09_2007_160253.ch_log
./Load_spcl_cldspn_trn3_Jun_10_2007_072059.log
./Load_spcl_cldspn_trn4_Jun_10_2007_072317.log
./Load_spcl_cldspn_trn6_Jun_10_2007_072717.log

and I wont to do this command
ls -tg

Maybe something like

$for i in `ls -tg`;do somecommand "i";done

From the command line you can use:

ls <file name> |  xargs <command for each line>
or

xargs -a <file name> <command for each line>
