Hi,
I have written a perl one liner that gets rid of
digits at the end of a word, but it also gets rid of
digits if they are at the beginning of a line.
The one liner is
perl -ne 's/([a-z]\d+)/$1/g;' <filename>
It doesn't work, but if I use it in a script it works.
I want to know where am I going wrong. Also I want to
know how to not get rid of digits at the beginning of
a line but the ones that follow some chars
If input is like the one below,
This23
is
a
45
good
thing
The result should be
This
is
a
45
good
thing
Thamks,
Anupama.

perl -pe 's/(\D+?)\d+/$1/g' <file>
That should work for your first problem.
Now the problem with your one liner ...
perl -ne 's/([a-z]\d+)/$1/g;' <filename>
-n option won't print the output, you got to use -p instead
[a-z] range will match exactly one character, not a word
