I have to write a shell script that takes a number as input , like 123
and the output will be 6 ,i.e the output will be the sum of digits of the input.
I have an idea as follows,
But the problem is after " echo "123"|fold -1|tr '\n' '+' " the output is 1+2+3+ which is not working with bc.
Is there is any way to replace the last character of a line to "\n" ???
Thanking You ,
M.Choudhury

Hi All,
I don't know what I am doing wrong in the regex below.
I have the following string:
31000000010201005181121360000000100000000003000000YYY-YYY-YYY-20100518-104139.txt.YYY
I need to split it in parts:
- Group 1: 3100000001020100518112136
- Group 2: 000000010
- Group 3:... (0 Replies)
cat input.txt
agsbdafgd
ertebrtreter
ahrbrwerg
The last character of a line that does not start with a would be changed to Z.
Final output:
agsbdafgd
ertebrtreteZ
ahrbrwerg
Can anyone post the sed command to do that? (2 Replies)

tclsh8.4
tclsh(1) Tcl Applications tclsh(1)__________________________________________________________________________________________________________________________________________________NAME
tclsh - Simple shell containing Tcl interpreter
SYNOPSIS
tclsh ?fileName arg arg ...?
_________________________________________________________________DESCRIPTION
Tclsh is a shell-like application that reads Tcl commands from its standard input or from a file and evaluates them. If invoked with no
arguments then it runs interactively, reading Tcl commands from standard input and printing command results and error messages to standard
output. It runs until the exit command is invoked or until it reaches end-of-file on its standard input. If there exists a file .tclshrc
(or tclshrc.tcl on the Windows platforms) in the home directory of the user, tclsh evaluates the file as a Tcl script just before reading
the first command from standard input.
SCRIPT FILES
If tclsh is invoked with arguments then the first argument is the name of a script file and any additional arguments are made available to
the script as variables (see below). Instead of reading commands from standard input tclsh will read Tcl commands from the named file;
tclsh will exit when it reaches the end of the file. The end of the file may be marked either by the physical end of the medium, or by the |
character, '
