Shell Programming and Scripting

If you cat command accepts -vet with no errors then unprintable characters are not the issue. What locale are you using - please output result of the locale command

Hi Jim

below is the o/p of locale command.

Code:

 
 locale
LANG=en_US
LC_COLLATE="en_US"
LC_CTYPE="en_US"
LC_MONETARY="en_US"
LC_NUMERIC="en_US"
LC_TIME="en_US"
LC_MESSAGES="en_US"
LC_ALL=

That "junk" is the UTF8 equivalent of the 0x2592 char, a special line drawing char on the apple, possibly a "block" element. And thats what we see three times in the line. Not sure if that makes sense in your /hosts line.

As RudiC has pointed out the characters look like the ancient CGA _Extended_ ROM characters, the UTF8 _equivalent_ of the ROM decimal character 177.

If you consider the string you want to correct as binary rather then pure text then both I and RudiC have pointed you to a method that may work.

As you have no idea without looking at the rawcode in binary format what the character really is then hexdump, od or xxd is really the only quick way to find out...
In this case three binary bytes per character as we are able to detect them through _copy_n_paste_.
Binary bytes E2, 96 and 92 thrice...

Using CygWin...

Code:

AMIGA:~> echo -n " 10.178.14.67▒▒▒ ac01sp02-vip" > /tmp/text
AMIGA:~> od -tx1 /tmp/text
0000000 20 31 30 2e 31 37 38 2e 31 34 2e 36 37 e2 96 92
0000020 e2 96 92 e2 96 92 20 61 63 30 31 73 70 30 32 2d
0000040 76 69 70
0000043

Hi Rudic/Wisecracker,

here my problem is i am not able to see those junk character when i vi or cat host file.

my only concern is how should i see those junk character.
is there any way to see. at present i am using secure CRT tool.

i Googled and found below script that helps in viewing junk character through vi.
but this script is showing the junk character only when viewing the file using latest putty version and not working when do vi in secure crt.

Code:

# cat read.sh
  #!/bin/sh
   
  while read N
  do
          if hasjunk "$N"
          then
               echo "$N"
          fi
  done

so here my only concern is to see/figure out junk character in a host file.
thx
