I am trying to show out the character count of a file if greater than 500 characters. When I do the -m its show the size of the file and not the characters in the file. Where am I getting confused? Or is -c and -m the same thing? Code is below
Code:
if [ "$(wc -m <$F)" -gt 500 ];
then
echo "Char count: $(wc -m <$F)"
echo "File $F has more than 500 Characters!"
exit
fi
I think you were actually writing the result to the file "500".
There's no need to run wc twice. The wasted time of running extra processes like that adds up real fast.
I made tar file having file names more character( up to 50).
When i extract file in Linux it extracts fine.. but in HPUX all file name which are more than 24 are trimed to 24 characters.
i m using "tar -xvf xx.tar"
i read some O and N option for New posix and Old but didnt got. :confused:

CW(7) Miscellaneous Information Manual CW(7)NAME
CW - the international Morse code
DESCRIPTION
CW is an abbreviation for "continuous wave", the commonly used technical term for Morse code communication. A basic knowledge or under-
standing of Morse code is a requirement for Radio Amateurs and Marine Radio Operators in many parts of the world.
MORSE CODE TIMINGS
In Morse code, a dot or dash is referred to as an element. The basic timing unit is the dot period. This is the time taken to send a dot,
not including any space before or after the dot. The lengths of all other elements are then derived from this basic unit, using the fol-
lowing rules:
The duration of a dash is three dots.
The time between each element (dot or dash) is one dot length.
The space between characters is three dot lengths.
The space between words is seven dot lengths.
The following formula calculates the dot period in microseconds from the Morse code speed in words per minute:
dot period = ( 1200000 / speed )
This formula arises from the use of the word PARIS as a 'standard' word for calibrating Morse code speed. PARIS is 50 units long when sent
in Morse code. Analysis of English plain-text indicates that the average word is 50 units, including spaces.
MORSE CODE CHARACTERS
The following list shows the IS0 8859-1 (Latin-1) characters that have commonly understood representations in Morse code:
ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"$()+-./:;=?_@ and space
In addition, following ISO 8859-1 and ISO 8859-2 accented characters are also part of the generally accepted international Morse code:
UACOEEANS (S with cedilla), (Z with caron/hacek),
Finally, libcw adds the following ASCII characters as extensions to single character procedural signals:
<>!&^~
MORSE CODE CHARACTER TABLES
The following table shows the Morse code equivalents for the ISO 8859-1, accented ISO 8859-1, and accented ISO 8859-2 characters above.
The ASCII portion of this table is taken from the ARRL Handbook, and the accented extensions from various other sources:
Ch Code Ch Code Ch Code Ch Code
-------------------------------------------------------
A .- B -... C -.-. D -..
E . F ..-. G --. H ....
I .. J .--- K -.- L .-..
M -- N -. O --- P .--.
Q --.- R .-. S ... T -
U ..- V ...- W .-- X -..-
Y -.-- Z --..
0 ----- 1 .---- 2 ..--- 3 ...--
4 ....- 5 ..... 6 -.... 7 --...

Ch Code Ch Code
-------------------------------------------------
U ..-- A .-.-
C -.-.. O ---.
E ..-.. A .-..-
A .--.- N --.--
S (S+cedilla) ---- (Z+caron/hacek) --..-
In addition to the above standard characters, the following characters are conventionally used for punctuation and procedural signals as
follows:
Ch Code Ch Code Ch Code Ch Code
-------------------------------------------------------
" .-..-. ' .----. $ ...-..- ( -.--.
) -.--.- + .-.-. , --..-- - -....-
. .-.-.- / -..-. : ---... ; -.-.-.
= -...- ? ..--.. _ ..--.- @ .--.-.
and the following are non-conventional extensions implemented by libcw:
Ch Code Ch Code Ch Code Ch Code
-----------------------------------------------------
< ...-.- > -...-.- ! ...-. & .-...
^ -.-.- ~ .-.-..
An alternative view of punctuation and procedural signals is as combination Morse characters:
Ch Prosig Ch Prosig Ch Prosig Ch Prosig
---------------------------------------------------------
" [AF] ' [WG] $ [SX] ( [KN]
) [KK] + [AR] , [MIM] - [DU]
. [AAA] / [DN] : [OS] ; [KR]
= [BT] ? [IMI] _ [IQ] @ [AC]
< [VA],[SK] > [BK] ! [SN] & [AS]
^ [KA] ~ [AL]
NOTES
Despite the fact that this manual page constantly and consistently refers to Morse code elements as dots and dashes, DO NOT think in these
terms when trying to learn Morse code. Always think of them as 'dit's and 'dah's.
