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
genotype.bim
snp1 ... A G
snp2 ... G T
snp3 ... G T
snp4 ... G A

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 and decode files
SYNOPSIS
[password]
DESCRIPTION
reads from the standard input and writes on the standard output. password is a key that selects a particular transformation. If no pass-
word is given, demands a key from the terminal and turns off printing while the key is being typed in. encrypts and decrypts with the same
key:
The latter command decrypts the file and prints the clear version.
Files encrypted by are compatible with those treated by the editor in encryption mode (see ed(1)).
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; "sneak paths" by which keys or clear text can become visible must be minimized.
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 widely known; thus provides minimal security.
The transformation of a key into the internal settings of the machine is deliberately designed to be expensive; that is, to take a substan-
tial fraction of a second to compute. However, if keys are restricted to, for example, three lowercase letters, then encrypted files can
be read by expending only a substantial fraction of five minutes of machine time.
Since the key is an argument to the command, it is potentially visible to users executing the or a derivative (see ps(1)). The choice of
keys and key security are the most vulnerable aspect of
EXAMPLES
The following example demonstrates the use of to edit a file that the user wants to keep strictly confidential:
...
...
...
Note that the option is the encryption mode of and prompts the user for the same key with which the file was encrypted.
WARNINGS
If output is piped to and the encryption key is given on the command line, can leave terminal modes in a strange state (see nroff(1) and
stty(1)).
If two or more files encrypted with the same key are concatenated and an attempt is made to decrypt the result, only the the first of the
original files is decrypted correctly.
