How could I check if a string variable contains at least (or only) 2 characters, and check and make sure that the string does not contain any numeric digits?...I need to know how to do this as simple as possible. and I am using the Ksh shell. Thanks. (1 Reply)
I've got a file (numbers.txt) filled with numbers and I want to replace each one of those numbers with a new random number between 0 and 9. This is my script so far:
#!/bin/bash
rand=$(($RANDOM % 9))
sed -i s//$rand/g numbers.txtThe problem that I have is that it replaces each number with just... (2 Replies)
hi
i am writing a hangman script and am having trouble checking the correct letters against the word
i need the script to compare the word against the letters guessed that are correct so once all the letters within the word have been guessed it will alow me to create a wining senario

While I do know some control characters need to be escaped, can normal characters also be escaped and still work the same way? Basically I do not know all control characters that have a special meaning, for example, ?, ., % have a meaning and have to be escaped... (11 Replies)

Hello, I am working with some very large files (upwards of 1M records). I have written code to parse out a lot of the data and am using awk rather than a built-in "while read LINE" for performance (I have tested both ways). That said, I now need to read each of these incoming lines, check the ninth... (2 Replies)
My question is basically as the title says. How can I check a user inputted string is only certain characters long (for example, 3 characters long) and how do I check a user inputted string only contains certain characters (for example, it should only contain the characters 'u', 'a', 'g', and 'c')...

SYNOPSIS
Functions/Subroutines
subroutine slags2 (UPPER, A1, A2, A3, B1, B2, B3, CSU, SNU, CSV, SNV, CSQ, SNQ)
SLAGS2 computes 2-by-2 orthogonal matrices U, V, and Q, and applies them to matrices A and B such that the rows of the transformed A
and B are parallel.
Function/Subroutine Documentation
subroutine slags2 (logicalUPPER, realA1, realA2, realA3, realB1, realB2, realB3, realCSU, realSNU, realCSV, realSNV, realCSQ, realSNQ)
SLAGS2 computes 2-by-2 orthogonal matrices U, V, and Q, and applies them to matrices A and B such that the rows of the transformed A and B
are parallel.
Purpose:
SLAGS2 computes 2-by-2 orthogonal matrices U, V and Q, such
that if ( UPPER ) then
U**T *A*Q = U**T *( A1 A2 )*Q = ( x 0 )
( 0 A3 ) ( x x )
and
V**T*B*Q = V**T *( B1 B2 )*Q = ( x 0 )
( 0 B3 ) ( x x )
or if ( .NOT.UPPER ) then
U**T *A*Q = U**T *( A1 0 )*Q = ( x x )
( A2 A3 ) ( 0 x )
and
V**T*B*Q = V**T*( B1 0 )*Q = ( x x )
( B2 B3 ) ( 0 x )
The rows of the transformed A and B are parallel, where
U = ( CSU SNU ), V = ( CSV SNV ), Q = ( CSQ SNQ )
( -SNU CSU ) ( -SNV CSV ) ( -SNQ CSQ )
Z**T denotes the transpose of Z.
Parameters:
UPPER
UPPER is LOGICAL
= .TRUE.: the input matrices A and B are upper triangular.
= .FALSE.: the input matrices A and B are lower triangular.
A1
A1 is REAL
A2

On entry, A1, A2 and A3 are elements of the input 2-by-2
upper (lower) triangular matrix A.
B1
B1 is REAL
B2
B2 is REAL
B3
B3 is REAL
On entry, B1, B2 and B3 are elements of the input 2-by-2
upper (lower) triangular matrix B.
CSU
CSU is REAL
SNU
SNU is REAL
The desired orthogonal matrix U.
CSV
CSV is REAL
SNV
SNV is REAL
The desired orthogonal matrix V.
CSQ
CSQ is REAL
SNQ
SNQ is REAL
The desired orthogonal matrix Q.
