I'm currently performing this using a one liner in bash... I'm a bit of a script noob.
When I add in cat -e I now see the wc -l output(3 in this case) at the end of the line (woot - no more overlapping output) with the characters you mentioned:
Code:
^M 3$

I did some more poking and piping my echo statement to
Code:
tr -dc '[:print:]'
cleared things up. How can I go back and identify what was causing the issue or was it wc's inherent output formatting?
Appreciate the assitance.

Thinking something is getting through with the files I'm pulling from.
I perform this with some made up files with basic strings and all is well. No overlapping funkiness:
Code:
file1:
windows 7
application 1
application 2
application 3
file2:
windows 7
application 1
application 2
application 3
application 4
application 5
> ls * | while read a; do printf "$a $(egrep "windows" $a) $(egrep application $a | wc -l)\n";done
file1 windows 7 3
file2 windows 7 5

Figured this out with the files I'm working with... tr -d '\r' removed the carriage return but I wasn't sure where since it worked when I put it after the echo statement. Moved it back, one at a time and see it needed to remove that from the first command substitution. All good now. Nothing to do with wc from the look of it at this point... just my own skewed perception.
ls * | while read a; do printf "$a $(egrep "text" $a | tr -d '\r') $(egrep other_text $a | wc -l)\n";done

I have a file, we'll call it file.txt. It has thousands of lines of all kinds of output at any given time (ie. foo bar foo bar)
I need to copy out just a portion of the file from Point-A to Point-B. I'd like to save off just that portion to a file called test123xyz.txt.
How do I do that?

tcl_substobj
Tcl_SubstObj(3tcl) Tcl Library Procedures Tcl_SubstObj(3tcl)__________________________________________________________________________________________________________________________________________________NAME
Tcl_SubstObj - perform substitutions on Tcl objects
SYNOPSIS
#include <tcl.h>
Tcl_Obj *
Tcl_SubstObj(interp, objPtr, flags)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter in which to execute Tcl scripts and lookup variables. If an error occurs, the interpreter's
result is modified to hold an error message.
Tcl_Obj *objPtr (in) A Tcl object containing the string to perform substitutions on.
int flags (in) ORed combination of flag bits that specify which substitutions to perform. The flags TCL_SUBST_COM-
MANDS, TCL_SUBST_VARIABLES and TCL_SUBST_BACKSLASHES are currently supported, and TCL_SUBST_ALL is pro-
vided as a convenience for the common case where all substitutions are desired.
_________________________________________________________________DESCRIPTION
The Tcl_SubstObj function is used to perform substitutions on strings in the fashion of the subst command. It gets the value of the string
contained in objPtr and scans it, copying characters and performing the chosen substitutions as it goes to an output object which is
returned as the result of the function. In the event of an error occurring during the execution of a command or variable substitution, the
function returns NULL and an error message is left in interp's result.
Three kinds of substitutions are supported. When the TCL_SUBST_BACKSLASHES bit is set in flags, sequences that look like backslash substi-
tutions for Tcl commands are replaced by their corresponding character.
When the TCL_SUBST_VARIABLES bit is set in flags, sequences that look like variable substitutions for Tcl commands are replaced by the con-
tents of the named variable.
When the TCL_SUBST_COMMANDS bit is set in flags, sequences that look like command substitutions for Tcl commands are replaced by the result
of evaluating that script. Where an uncaught "continue exception" occurs during the evaluation of a command substitution, an empty string
is substituted for the command. Where an uncaught "break exception" occurs during the evaluation of a command substitution, the result of
the whole substitution on objPtr will be truncated at the point immediately before the start of the command substitution, and no characters
will be added to the result or substitutions performed after that point.
