When I create a newfile, I am using the filename as a variable to create the new filename. When I ouput it, the filename contains the file extension in the middle of the file
example:
router1.txtshcdpneighbors.txt
router2.logshcdpneighbors.txt
My initial approach was to strip it out, now I would like to strip out .txt or .log. How can I add an or statement to the for in statement?
If have
var='$variable'
how can I expand $variable.
I have tried many thing like duble quotes/braces etc, but nothing worked.

Sorry for such a dreadful title, but I'm not sure how to be more descriptive. I'm hoping some of the more gurutastic out there can take a look at a solution I came up with to a problem, and advice if there are better ways to have gone about it.

I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.
As an example I've written a script called question (The fist command is to show what is the contents of the... (2 Replies)
Hi,
I'm using a for loop reading from an input file that contains files, whose path includes a variable name.
But the for loop doesn't expand the variable and therefore can't find the file.
Here's an example:

I need some help to write a ksh script.
My code so far (pretty bad, sorry):

while test $UserDecision = y

read Number1
echo "Enter a number: "

Hi I want to write a script such that when executed, it will store all input as different variable, for eg
./store.sh name1 name2 name3 name4
will result in
$1=name1
$2=name2
$3=name3
etc
How do I do that?
Thanks. (1 Reply)
Hi,
I have done the scripting such that it will read input line by line from a txt file and is passed through a script, but now my requirement is to pass two variables into a script from a file, how could I do this or is there any other better idea ?

Hi All,
I have to insert 2 values to a text file in specific places. I have been able to extract each variable value via a script but am not able to send these variable values to the text file.
Pasted is the script for extracting the variable values:

Hello all,
I've been out of programming for awhile so sorry about the stupid, elementary question.
I'm trying to read two inputs and compare them to a list entered as a parameter via the terminal. The script is

Hi guys!
Kind of new to bash scripting and now I'm stuck.
I need to curl with these variables:

and my input_file.txt contains

extend
extend(1) General Commands Manual extend(1)NAME
extend -- produce an extended elevation from a .3d file
SYNOPSIS
extend [--specfile configuration .espec file] input .3d file [output .3d file]
Description
Note:
The extend program can also work on Compass .plt (as can aven and any other Survex program which reads .3d files).
If no specfile is given, extend starts with the highest station marked as an entrance which has at least one underground survey leg
attached to it. If there are no such stations, the highest deadend station in the survey (or the highest station if there are no deadends)
is used. Extend puts the first station on the left, then folds each leg out individually to the right, breaking loops arbitrarily (usually
at junctions).
If the output filename is not specified, extend bases the output filename on the input filename, but ending "_extend.3d". For example,
extend deep_pit.3d produces an extended elevation called deep_pit_extend.3d.
This approach suffices for simple caves or sections of cave, but for more complicated situations human intervention is required. More com-
plex sections of cave can be handled with a specfile giving directions to switch the direction of extension between left and right, to
explicitly specify the start station, or to break the extension at particular stations or legs.
The specfile is in a format similar to cavern's data format:
;This is a comment
; start the elevation at station entrance.a
*start entrance.a ;this is a comment after a command
; start extending leftwards from station half-way-down.5
*eleft half-way-down.5
; change direction of extension at further-down.8
*eswap further-down.8
; extend right from further-down.junction, but only for
; the leg joining it to very-deep.1, other legs continuing
; as before
*eright further-down.junction very-deep.1
; break the survey at station side-loop.4
*break side-loop.4
; break survey at station side-loop.junction but only
; for leg going to complex-loop.2
*break side-loop.junction complex-loop.2
This approach requires some trial and error, but gives useful results for many caves. The most complex systems would benefit from an
interactive interface to select and view the breaks and switches of direction.
