Shell Programming and Scripting

suppose have different files
1.1
2.2
3.3
4.4
5.5

All the files have to run under the same command say
tr -d '\n'

so how to run all the files under the same command by using shell script

Do you mean removing all linefeed characters ...

for d in *.*
do
   tr -d '\n' <$d >tmp
   mv tmp $d
done

Simply having all those files say abc,def,ghi,fdg,dgg
and print the new files
can i follow like that
for d in abc, def, ghi, fdg, dgg
do
tr -d '\n' <$d >tmp
mv tmp $d
done

or what else give option
thanks

what are the commas for?

The "for" statement takes elements separated by the normal white space rule.

I thought you wanted the files changed, not printed, hence the ">tmp" and "mv tmp $d".

man tr
