Sample log output from another log file...
before - echoed out as is (without your suggestion (the website doesn't show all the blanks after the **** and before the first word though):
**** Test file processed for 02/24/2003 completed.
**** Datetime: Tue 02/25/2003 10:59:20
******************************************************************************
after - using your suggestion (echoed out w/suggestion as is, and then after I cut the lines). The space between the **** and the word Test reduced to 1 blank character versus 10 or so:
**** Test file processed for 02/24/2003 completed.
**** Test file processed for
**** Datetime: Tue 02/25/2003 10:59:20
**** Datetime: Tue
******************************************************************************
******************************************************************************
If I compare just the last line (even with the cut command) script executes find and return 0.
If I compare the first two lines (&&), it fails every single time.
Not sure what is happening...to me the characters match character for character.
I don't know what is causing this behaviour.
Grazie.
Gianni

NAME
textutil::trim - Procedures to trim strings
SYNOPSIS
package require Tcl 8.2
package require textutil::trim ?0.7?
::textutil::trim::trim string ?regexp?
::textutil::trim::trimleft string ?regexp?
::textutil::trim::trimright string ?regexp?
::textutil::trim::trimPrefix string prefix
::textutil::trim::trimEmptyHeading string
_________________________________________________________________
DESCRIPTION
The package textutil::trim provides commands that trim strings using arbitrary regular expressions.
The complete set of procedures is described below.
::textutil::trim::trim string ?regexp?
Remove in string any leading and trailing substring according to the regular expression regexp and return the result as a new
string. This is done for all lines in the string, that is any substring between 2 newline chars, or between the beginning of the
string and a newline, or between a newline and the end of the string, or, if the string contain no newline, between the beginning
and the end of the string. The regular expression regexp defaults to "[ \t]+".
::textutil::trim::trimleft string ?regexp?
Remove in string any leading substring according to the regular expression regexp and return the result as a new string. This apply
on any line in the string, that is any substring between 2 newline chars, or between the beginning of the string and a newline, or
between a newline and the end of the string, or, if the string contain no newline, between the beginning and the end of the string.
The regular expression regexp defaults to "[ \t]+".
::textutil::trim::trimright string ?regexp?
Remove in string any trailing substring according to the regular expression regexp and return the result as a new string. This apply
on any line in the string, that is any substring between 2 newline chars, or between the beginning of the string and a newline, or
between a newline and the end of the string, or, if the string contain no newline, between the beginning and the end of the string.
The regular expression regexp defaults to "[ \t]+".
::textutil::trim::trimPrefix string prefix
Removes the prefix from the beginning of string and returns the result. The string is left unchanged if it doesn't have prefix at
its beginning.
::textutil::trim::trimEmptyHeading string
Looks for empty lines (including lines consisting of only whitespace) at the beginning of the string and removes it. The modified
string is returned as the result of the command.
