Hi,
I need to insert strings "0000 00" at the each line within the file.
The postion is 37 to 42.
ex.
name1 name2 0000 00
nam name 0000 00
The "0000 00" in two lines should be lined up.
I don't know why it's not lined up when I posted it.
Can anyone help? (14 Replies)

Hello,
I would like to find an efficient way to compare a pair of strings that differ at one position, and return the difference and position.
For example:
String1 123456789
String2 123454789
returning something - position 6, 6/4
Thanks in advance,
Mike (5 Replies)
Hi,
I need to search for some strings in specific positions in a file.
If the strings: "foo1", "foo2" or "foo3" is on position 266 or position 288 in a file i want the whole line printed.
Any idea how to do it? (5 Replies)
HI All,
am trying to find the position of space in a variable, it is working for other characters other than space
ulab="ulab1|ulab2"
find_pos=`expr index $ulab '|'`
echo $find_pos
above code worked fine but below one says syntax error
ulab="ulab ulab2"
find_pos=`expr index $ulab ' '`... (2 Replies)
i have a requirement like this
if the line contains from position 294 to 299 is equal to "prabhu" ,then print entire line .
i want to use awk

I am not an expert with linux, but following various posts on this forum, I have been trying to write a script to match pattern of charters occurring together in a file.
My file has approximately 200 million characters (upper and lower case), with about 50 characters per line. I have merged all... (5 Replies)

sum(3tcl) Cyclic Redundancy Checks sum(3tcl)__________________________________________________________________________________________________________________________________________________NAME
sum - Calculate a sum(1) compatible checksum
SYNOPSIS
package require Tcl 8.2
package require sum ?1.1.0?
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
_________________________________________________________________DESCRIPTION
This package provides a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data. The
BSD sum algorithm is used by default but the SysV algorithm is also available.
COMMANDS
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
The command takes string data or a file name or a channel and returns a checksum value calculated using the sum(1) algorithm. The
result is formatted using the format(3tcl) specifier provided or as an unsigned integer (%u) by default.
OPTIONS -sysv The SysV algorithm is fairly naive. The byte values are summed and any overflow is discarded. The lowest 16 bits are returned as the
checksum. Input with the same content but different ordering will give the same result.
-bsd This algorithm is similar to the SysV version but includes a bit rotation step which provides a dependency on the order of the data
values.
-filename name
Return a checksum for the file contents instead of for parameter data.
-channel chan
Return a checksum for the contents of the specified channel. The channel must be open for reading and should be configured for
binary translation. The channel will no be closed on completion.
-chunksize size
Set the block size used when reading data from either files or channels. This value defaults to 4096.
-format string
Return the checksum using an alternative format template.
EXAMPLES
% crc::sum "Hello, World!"
37287
% crc::sum -format 0x%X "Hello, World!"
0x91A7
% crc::sum -file sum.tcl
