Hi all,

Please help me to remove first and last character of each line in a file.

Thanks,

Hi,

I think all previous solutions remove a leading and trailing blank space if exist. If you want to omit them, try next perl command. One example:

$ cat infile
monday
  tuesday
wednesday   
        thursday
friday
$ cat -A infile
monday$
  tuesday$
wednesday   $
^Ithursday^I$
friday$
$ sed 's/.\(.\+\).$/\1/' infile
onda
 tuesda
ednesday  
thursday
rida
$ sed 's,^.,,g;s,.$,,g' infile
onda
 tuesda
ednesday  
thursday
rida
$ sed 's/.\(.*\)./\1/' infile
onda
 tuesda
ednesday  
thursday
rida
$ perl -lpe 's/\S//; s/\S(\s*)$//' infile
onda
  uesda
ednesda
        hursda
rida
