needs to be in bash i believe. Im not to sure as our lecturer or tutor hasnt specified this POSIX term. And in the lecture slide > and < can be used to compare string values apparently.
Hi,
I trying to find the solution for writing the programming in unix by shell programming for sorting thr string in alphabetical order.
I getting diffculty in that ,, so i want to find out the solution for that
Please do needful
Thanks

echo $TEMP|grep ""
I want to check TEMP is alphabetic or not in both the cases.but in above script i am getting 1($?) if TEMP is in pure lower case or pure upper case.i want to get 0($?) when TEMP would be alphabetic in either cases.pleaaaase help me out..... (4 Replies)
Hi all,
I So, I've got a monster text document comprising a list of various company names and associated info just in a long list one after another. I need to sort them alphabetically by name...
The text document looks like this:
Company Name:
the_first_company's_name_here
Address:... (2 Replies)
Hi everyone!
I am new to the forum and have recently started working with Linux.
Quick question, I want a user list in alphabetical order as the output of a shell script.
Who can help me!?
Thanks!

I've looking over a script for work and I've had a problem with the script not listing the files in alphabetical order. To look up PIDs for apps, it would be beneficial to have them listed in that order. Here is what I've been reviewing.

Hi, need help in sorting lines between strings "<section status = “ole-service”>" and "</section>" in alphabetical order, based on the text in red. Hoping for an AWK or SED solution. Thank you.

bc
BC(1) General Commands Manual BC(1)NAME
bc - arbitrary-precision arithmetic language
SYNOPSIS
bc [ -c ] [ -l ] [ file ... ]
DESCRIPTION
Bc is an interactive processor for a language which resembles C but provides unlimited precision arithmetic. It takes input from any files
given, then reads the standard input. The -l argument stands for the name of an arbitrary precision math library. The syntax for bc pro-
grams is as follows; L means letter a-z, E means expression, S means statement.
Comments
are enclosed in /* and */.
Names
simple variables: L
array elements: L [ E ]
The words `ibase', `obase', and `scale'
Other operands
arbitrarily long numbers with optional sign and decimal point.
( E )
sqrt ( E )
length ( E ) number of significant decimal digits
scale ( E ) number of digits right of decimal point
L ( E , ... , E )
Operators
+ - * / % ^ (% is remainder; ^ is power)
++ -- (prefix and postfix; apply to names)
== <= >= != < >
= += -= *= /= %= ^=
Statements
E
{ S ; ... ; S }
if ( E ) S
while ( E ) S
for ( E ; E ; E ) S
null statement
break
quit
Function definitions
define L ( L ,..., L ) {
auto L, ... , L
S; ... S
return ( E )
}
Functions in -l math library
s(x) sine
c(x) cosine
e(x) exponential
l(x) log
a(x) arctangent
j(n,x) Bessel function
All function arguments are passed by value.
The value of a statement that is an expression is printed unless the main operator is an assignment. Either semicolons or newlines may
separate statements. Assignment to scale influences the number of digits to be retained on arithmetic operations in the manner of dc(1).
Assignments to ibase or obase set the input and output number radix respectively.
The same letter may be used as an array, a function, and a simple variable simultaneously. All variables are global to the program.
`Auto' variables are pushed down during function calls. When using arrays as function arguments or defining them as automatic variables
empty square brackets must follow the array name.
For example
scale = 20
define e(x){
auto a, b, c, i, s
a = 1
b = 1
s = 1
for(i=1; 1==1; i++){
a = a*x
b = b*i
c = a/b
if(c == 0) return(s)
s = s+c
}
}
defines a function to compute an approximate value of the exponential function and
for(i=1; i<=10; i++) e(i)
prints approximate values of the exponential function of the first ten integers.
Bc is actually a preprocessor for dc(1), which it invokes automatically, unless the -c (compile only) option is present. In this case the
dc input is sent to the standard output instead.

No &&, ||, or ! operators.
For statement must have all three E's.
Quit is interpreted when read, not when executed.
