Hi,
I need to find whether the first character in a line is a alphabet or a number. If its a number i should sort it numerically. If its a alphabet i should sort it based on the ASCII value.And if it is something other than alphabet or number then sort it based on ASCII value.
The code i used... (2 Replies)

Hello,
I have to find out whether the last character is digit or alphabet. I manage to strip the last character but would need some help if there is one liner available to test the above.
set x = WM
echo $x | sed 's/.*\(.$\)/\1/'
O/P
M
I would like a one liner code to test whether the... (1 Reply)
I have a genotype.bim file where it contains information about SNPs and genotype. As a hypothetical example, let's say

snpN ... C G
where first column identifies each SNP and 5th and 6th column has genotype... (3 Replies)
Hello all,
I am in a middle of an assignment and i would appreciate any help.
How can i write a bash shell script code that checks if all elements in an array are the same numbers. I mean -->array = ( 0,0,0,0,0 )
( e.g., if
then return "OK'
fi )
Thank you in advance, (9 Replies)

I wanted to know if there was a more efficient to do this. I was to setup a conditional for every letter of the alphabet, like so (I am parsing an array):
for i in "${arr}"; do
if ]; then
echo "$i starts with A"
else echo "$i does not start with A"
fi
done
I want to do this A-Z, is there... (6 Replies)

crypt
crypt(1) General Commands Manual crypt(1)Name
crypt - encode/decode (available only if the Encryption layered product is installed)
Syntax
crypt key < input.File > output.File
Description
This reference page describes software that is available only if the Encryption layered product is installed.
The command reads from the standard input and writes on the standard output. You must supply a key which selects a particular transforma-
tion. If no password is given, demands a key from the terminal and turns off printing while the key is being typed in. The command
encrypts and decrypts with the same key.
Files encrypted by are compatible with those treated by the ed, ex and vi editors in encryption mode.
The security of encrypted files depends on three factors: the fundamental method must be hard to solve, direct search of the key space must
be infeasible, and sneak paths by which keys or clear text can become visible must be minimized.
The command implements a one-rotor machine designed along the lines of the German Enigma, but with a 256-element rotor. Methods of attack
on such machines are known, but not widely; moreover the amount of work required is likely to be large.
The transformation of a key into the internal settings of the machine is deliberately designed to be expensive, for example, to take a sub-
stantial fraction of a second to compute. However, if keys are restricted to three lowercase letters, then encrypted files can be read by
expending only a substantial fraction of five minutes of machine time.
Since the key you choose is an argument to the command, it is potentially visible to users executing ps(1) or a derivative. To minimize
this possibility, destroys any record of the key immediately upon entry. The most vulnerable aspect of is the choice of keys and key secu-
rity.
Examples
The following examples use KEY as the key to encrypt and decrypt files. The first example encrypts the file naming the resulting encrypted
file The second example decrypts the file naming the resulting decrypted file The third example prints the encrypted file in clear text.
crypt KEY < plain.File > crypt.File
crypt KEY < crypt.File > decrypt.File
