We have a non printable character "®" in our file , we want to remove this character, we tried
Code:
tr -dc '[:print:]' < oldfile> newfile
but this command is removing all new line entries along with the non printable character and all the records are coming in one line(it is changing the format of the file). please advise.
I need to check ftp'd incoming files for characters that are not alphanumeric,<tab>, <cr>, or <lf> characters. Each file would have 10-20,000 line with up to 3,000 characters per line. Should I use awk, sed, or grep and what would the command look like to do such a search? Thanks much to anyone... (2 Replies)
Sometimes obvious things... are not so obvious. I always thought that it was possible to grep non printable characters but not with my GNU grep (5.2.1) version.
printf "Hello\tWorld" | grep -l '\t'
printf "Hello\tWorld" | grep -l '\x09'
printf "Hello\tWorld" | grep -l '\x{09}'
None of them... (3 Replies)

Hi All,
I am trying to find non-printable characters in a string. The sting could have alphanumeric, puntuations and characters like (*&%$#.') but not non-printable (or that is what I think they are called) which are introduced when you copy any text from DOS to unix box.

FBB::mlm(3bobcat) OFoldStream manipulator FBB::mlm(3bobcat)NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request
then left margin 0 will silently be used.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be added to the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
the next word inserted into that line (cf., the example section below)
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.
