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)crypt(1)NAME
crypt - encode or decode a file
SYNOPSIS
crypt [password]
The crypt utility encrypts and decrypts the contents of a file. crypt reads from the standard input and writes on the standard output. The
password is a key that selects a particular transformation. If no password is given, crypt demands a key from the terminal and turns off
printing while the key is being typed in. crypt encrypts and decrypts with the same key:
example% crypt key < clear.file > encrypted.file
example% crypt key < encrypted.file | pr
prints the contents of clear.file.
Files encrypted by crypt are compatible with those treated by the editors ed(1), ex(1), and vi(1) 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; "sneak paths" by which keys or cleartext can become visible must be minimized.
crypt 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 crypt 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 (say) three lower-case 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 crypt command, it is potentially visible to users executing ps(1) or a derivative command. To minimize
this possibility, crypt takes care to destroy any record of the key immediately upon entry. No doubt the choice of keys and key security
are the most vulnerable aspect of crypt.
