Hello Corona,
Thanks for answer. I'll try to answer.

304 is only 3 digits length:
First digit=3
Second digit=0
Then I need to expand only the range that contains the given number, this is expand the 30X, where X=0-9. 31X and 32X are no expanded
since the goal is to show the output the most compact as possible and only expand as needed to show the given numbers (in this case 304, 3357).

3357 is only 4 digits length:
First digit=3
Second digit=3
Third digit=5
Then I need to expand/open only the series 335X. And to expand 335X, first I need to expand the range 33X since 335X is inside 33X.

The 2-digit ranges should be present if the given numbers are not inside them, since the range 3X is being expanded and the expansion should
contain all numbers that begin with 3 once is expanded. For example, if I only expand the series 30X and 335X without showing 38X, 39X, etc,
the output list won't be representing all numbers that begin with 3.
Thanks again.

Folks,
Is there a simple way to replace one digit by two digit using sed.
Example,
mydigit1918_2006_8_8_lag1.csv should be
mydigit1918_2006_08_08_lag01.csv.
I tried this way, but doesn't work.
echo mydigit1989_2006_8_8_lag1.csv|sed 's/]/0]/'

divide input values into specified number (-100 or -200) according to the key (a1 or a2 ....)
For ex: if we give -100 in the command line it would create 100 number intervals (1-100, 100-200, 200-300) untill it covers the value 300 in a1.
Note: It should work the same even with huge numbers... (3 Replies)

Hi,
I've been working on a few scripts and have been getting great info.
How, would I include in the below script, how I would let a user know that if they divide a SECOND number by zero, that they would get a divide by zero error? What's the easiest way of working this?
Cordially,

expand
EXPAND(1) BSD General Commands Manual EXPAND(1)
NAME
expand, unexpand -- expand tabs to spaces, and vice versa
SYNOPSIS
expand [-t tab1,tab2,...,tabn] [file ...]
unexpand [-a | -t tab1,tab2,...,tabn] [file ...]
DESCRIPTION
The expand utility processes the named files or the standard input writing the standard output with tabs changed into blanks. Backspace
characters are preserved into the output and decrement the column count for tab calculations. The expand utility is useful for pre-process-
ing character files (before sorting, looking at specific columns, etc.) that contain tabs.
The unexpand utility puts tabs back into the data from the standard input or the named files and writes the result on the standard output.
The following options are available:
-a (unexpand only.) By default, only leading blanks and tabs are reconverted to maximal strings of tabs. If the -a option is given,
then tabs are inserted whenever they would compress the resultant file by replacing two or more characters.
-t tab1,tab2,...,tabn
Set tab stops at column positions tab1, tab2, ..., tabn. If only a single number is given, tab stops are set that number of column
positions apart instead of the default number of 8.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of expand and unexpand as described in environ(7).
EXIT STATUS
The expand and unexpand utilities exit 0 on success, and >0 if an error occurs.
STANDARDS
The expand and unexpand utilities conform to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The expand command appeared in 3.0BSD.
