Hi ,
I have a peculiar case, where my sed command is working on a file which contains lines of small length.
sed "s/XYZ:1/XYZ:3/g" abc.txt > xyz.txt
when abc.txt contains lines of small length(currently around 80 chars) , this sed command is working fine.
when abc.txt contains lines of... (3 Replies)
Hi experts.
I got a file (500mb max) and need to pivot it (loading into ORCL) and change BLANK delimiter to PIPE |.
Sometimes there are multipel BLANKS (as a particular value may be BLANK, or simply two BLANKS instead of one BLANK).
thanks for your input!
Cheers,

Hi all,
I am using Sed to convert a log file into a csv, so far so good. Kudos to this forum for helping me thus far!
My current problem. There are some lines in the log file that I do not want. How can I delete lines where the line legth is less than say 100?
Here are some sample lines... (6 Replies)
I have one base file, and multiple target files-- each have uniform line structure so no need to use grep to find things-- can just define sections by line number.
My question is quite simple-- can I use sed to copy a defined block of lines (say lines 5-10) from filename1.txt to overwrite an... (3 Replies)
Hi everyone,
I have two files (A and B) and want to combine them to one by always taking 10 rows from file A and subsequently 6 lines from file B. This process shall be repeated 40 times (file A = 400 lines; file B = 240 lines).
Does anybody have an idea how to do that using perl, awk or sed?... (6 Replies)
I have a diff command that does what I want but when comparing large text/log files, it uses up all the memory I have (sometimes over 8gig of memory)
diff file1.txt file2.txt | grep '^<'| awk '{$1="";print $0}' | sed 's/^ *//'
Is there a better more efficient way to find the lines in one file... (5 Replies)
Hello,
I have a file with a date field with various lengths. For example:
m/d/yyyy hh:mm or h:mm
mm/dd/yyyy hh:mm or h:mm
Is there a way using sed or awk to change the field to m/d/y ? I don't need the hours and minutes in that field, just the date in the proper format.
Thanks in... (6 Replies)

uuencode
uuencode(n) Text encoding & decoding binary data uuencode(n)
__________________________________________________________________________________________________________________________________________________NAME
uuencode - UU-encode/decode binary data
SYNOPSIS
package require Tcl 8
package require uuencode ?1.1.4?
::uuencode::encode string
::uuencode::decode string
::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)
::uuencode::uudecode (-file filename | ?--? string)
_________________________________________________________________DESCRIPTION
This package provides a Tcl-only implementation of the uuencode(1) and uudecode(1) commands. This encoding packs binary data into printable
ASCII characters.
::uuencode::encode string
returns the uuencoded data. This will encode all the data passed in even if this is longer than the uuencode maximum line length. If
the number of input bytes is not a multiple of 3 then additional 0 bytes are added to pad the string.
::uuencode::decode string
Decodes the given encoded data. This will return any padding characters as well and it is the callers responsibility to deal with
handling the actual length of the encoded data. (see uuencode).
::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)
::uuencode::uudecode (-file filename | ?--? string)
UUDecode a file or block of data. A file may contain more than one embedded file so the result is a list where each element is a
three element list of filename, mode value and data.
OPTIONS -filename name
Cause the uuencode or uudecode commands to read their data from the named file rather that taking a string parameter.
-name string
The uuencoded data header line contains the suggested file name to be used when unpacking the data. Use this option to change this
from the default of "data.dat".
-mode octal
The uuencoded data header line contains a suggested permissions bit pattern expressed as an octal string. To change the default of
0644 you can set this option. For instance, 0755 would be suitable for an executable. See chmod(1).
EXAMPLES
% set d [uuencode::encode "Hello World!"]
2&5L;&\@5V]R;&0A
% uuencode::uudecode $d
Hello World!
% set d [uuencode::uuencode -name hello.txt "Hello World"]
begin 644 hello.txt
+2&5L;&@5V]R;&0`
`
end
% uuencode::uudecode $d
{hello.txt 644 {Hello World}}
