Hello! I'm just learning the shell, and I would really like to know how to do this:
Given these 2 commands:
ls -l
ls -le
How can I, with a one-liner, ask the shell to show me visually in the shell, what the difference is between the output of the two commands? They look the same to me... (6 Replies)

In the awk I am trying to subtract the difference $3-$2 of each matching $4 before the first _ (underscore) and print that value in $13.
I think the awk will do that, but added comments. What I am not sure off is how to add a line or lines that will add sum each matching $13 value and put it in... (2 Replies)

cksum
cksum(3tcl) Cyclic Redundancy Checks cksum(3tcl)__________________________________________________________________________________________________________________________________________________NAME
cksum - Calculate a cksum(1) compatible checksum
SYNOPSIS
package require Tcl 8.2
package require cksum ?1.1.3?
::crc::cksum ?-format format? ?-chunksize size? [ -channel chan | -filename file | string ]
::crc::CksumInit
::crc::CksumUpdate token data
::crc::CksumFinal token
_________________________________________________________________DESCRIPTION
This package provides a Tcl implementation of the cksum(1) algorithm based upon information provided at in the GNU implementation of this
program as part of the GNU Textutils 2.0 package.
COMMANDS
::crc::cksum ?-format format? ?-chunksize size? [ -channel chan | -filename file | string ]
The command takes string data or a channel or file name and returns a checksum value calculated using the cksum(1) algorithm. The
result is formatted using the format(3tcl) specifier provided or as an unsigned integer (%u) by default.
OPTIONS -channel name
Return a checksum for the data read from a channel. The command will read data from the channel until the eof is true. If you need
to be able to process events during this calculation see the PROGRAMMING INTERFACE section
-filename name
This is a convenience option that opens the specified file, sets the encoding to binary and then acts as if the -channel option had
been used. The file is closed on completion.
-format string
Return the checksum using an alternative format template.
PROGRAMMING INTERFACE
The cksum package implements the checksum using a context variable to which additional data can be added at any time. This is expecially
useful in an event based environment such as a Tk application or a web server package. Data to be checksummed may be handled incrementally
during a fileevent handler in discrete chunks. This can improve the interactive nature of a GUI application and can help to avoid excessive
memory consumption.
::crc::CksumInit
Begins a new cksum context. Returns a token ID that must be used for the remaining functions. An optional seed may be specified if
required.
::crc::CksumUpdate token data
Add data to the checksum identified by token. Calling CksumUpdate $token "abcd" is equivalent to calling CksumUpdate $token "ab"
followed by CksumUpdate $token "cb". See EXAMPLES.
::crc::CksumFinal token
Returns the checksum value and releases any resources held by this token. Once this command completes the token will be invalid. The
result is a 32 bit integer value.
EXAMPLES
% crc::cksum "Hello, World!"
2609532967
% crc::cksum -format 0x%X "Hello, World!"
0x9B8A5027
% crc::cksum -file cksum.tcl
1828321145
% set tok [crc::CksumInit]
% crc::CksumUpdate $tok "Hello, "
% crc::CksumUpdate $tok "World!"
% crc::CksumFinal $tok
