I need to create a script that gets a positive number n as an argument. The script must calculate the factorial of its argument. In other words, it must calculate n!=1x2x3x...xn. Note that 0!=1.

I have a file that has the words I want to find in other files (but lets say I just want to find my words in a single file). Those words are IDs, so if my word is ZZZ4, outputs like aaZZZ4, ZZZ4bb, aaZZZ4bb, ZZ4, ZZZ, ZyZ4, ZZZ4.8 (or anything like that) WON'T BE USEFUL.
I need the whole word... (6 Replies)

Dear All,
assume i have a file with content:
<Start>6000</Start>

how should we use any awk, sed, perl can do this task, means to extract the uniq prefixes from the start and stop prefix.

environ
environ(5) File Formats Manual environ(5)NAME
environ - User environment
SYNOPSIS
extern char **environ;
DESCRIPTION
An array of strings called the environment is made available by the execve() function when a process begins. By convention these strings
have the form name=value. The following names are used by various commands: A startup list of commands read by ex, edit, and vi. A user's
login directory, set by login from the password file passwd. The sequence of directories, separated by colons, searched by csh, sh, sys-
tem, execvp, etc, when looking for an executable file. PATH is set to :/usr/ucb:/bin:/usr/bin initially by login. The name of the default
printer to be used by lpr, lpq, and lprm. The full pathname of the user's login shell. The kind of terminal for which output is to be
prepared. This information is used by commands, such as nroff which may exploit special terminal capabilities. The string describing the
terminal in the TERM environment variable, or, if it begins with a / (slash), the name of the termcap file. See TERMPATH below. A sequence
of pathnames of termcap files, separated by colons or spaces, which are searched for terminal descriptions in the order listed. Having no
TERMPATH is equivalent to a TERMPATH of $HOME/.termcap:/etc/termcap. TERMPATH is ignored if TERMCAP contains a full pathname. The login
name of the user.
Further names may be placed in the environment by the export command and name=value arguments in sh, or by the setenv command if you use
csh. It is unwise to change certain sh variables that are frequently exported by files, such as MAIL, PS1, PS2, and IFS.
