There is no range command.
A string with spaces is assigned to a simple variable.
The unquoted $range lets the shell break the string into tokens, so there is a loop over all tokens.

Hello guys.
In my script, i have the following code:
echo "The tarfile contains these directorys"
tar -tf file.tar > tarlist.txt
cat tarlist | awk -F/ '{print $1 "/" $2}' | nl
echo "Enter path of the directory you want to extract or just press enter to extract everything: "
read path... (1 Reply)
I need to check if $1 or $2 are empty before continuing but I don't know if bash has any logic of the sort. This is what I'm looking for - except that "and" doesn't seem to work.
if and ;then

Thank you! :D (4 Replies)
hi all i am trying to save an awk value into an array in bash:
total=`awk '{sum+=$3} END {print sum}' "$count".txt"`
((count++))
the above statement is in a while loop..
$count is to keep track of file numbers (1.txt,2.txt,3.txt,etc.)
i get the following error:

Apologies for the utter triviality of this question, but we all have to start somewhere! I've also tried searching but this question is pretty vague so I didn't (a) really know what to search for or (b) get many relevant hits to what I did search for.
Anyway, I'm in the process of self-teaching... (1 Reply)
Hi!
Been working on a script and I've been having a problem. I've finally narrowed it down to this variable I'm setting:
servername=$(awk -v FS=\/ '{ print $7 } blah.txt | sed 's\/./-/g' | awk -v FS=\- '{print $1}')"
This will essentially pare down a line like this:

Hi gurus,
I need to create arrays from variables, via a loop.
The issue I have is with the array name creation. How do I use a variable to define an array?
I want to do something like
declare -a $H
where $H is my loop variable.
I then need to add items to each array I've created,... (3 Replies)
I am new to ksh scripting, specially array. How do i get values from an array and set the value as variable and pass those variables to the different functions??
someone taught me how to get input from a file with have columns i need to read, but now i doesnt know how to set those value to be a... (7 Replies)
Hi,
Will following set up work in bash script? I've got errors if assigning following binary command to a variable. But on the other hand, COMMAND="ls" works. Any explanation please? How can I assign binary command to a variable COMMAND then I can just call ${COMMAND}?

Hello,
I have a simple task and I am having some trouble with the syntax. I have a variable with an assigned value,
CMD_STRING='-L 22 -s 0 -r -O -A i -N 100 -n'
I would like to add that variable to an array. As far as I have been able to look up, the syntax should be something like,

gltransformfeedbackvaryings
GLTRANSFORMFEEDBACKV(3G) OpenGL 3.3 GLTRANSFORMFEEDBACKV(3G)NAME
glTransformFeedbackVaryings - specify values to record in transform feedback buffers
C SPECIFICATION
void glTransformFeedbackVaryings(GLuintprogram, GLsizeicount, const char **varyings, GLenumbufferMode);
PARAMETERS
program
The name of the target program object.
count
The number of varying variables used for transform feedback.
varyings
An array of count zero-terminated strings specifying the names of the varying variables to use for transform feedback.
bufferMode
Identifies the mode used to capture the varying variables when transform feedback is active. bufferMode must be GL_INTERLEAVED_ATTRIBS
or GL_SEPARATE_ATTRIBS.
DESCRIPTION
The names of the vertex or geometry shader outputs to be recorded in transform feedback mode are specified using
glTransformFeedbackVaryings. When a geometry shader is active, transform feedback records the values of selected geometry shader output
variables from the emitted vertices. Otherwise, the values of the selected vertex shader outputs are recorded.
The state set by glTranformFeedbackVaryings is stored and takes effect next time glLinkProgram() is called on program. When glLinkProgram()
is called, program is linked so that the values of the specified varying variables for the vertices of each primitive generated by the GL
are written to a single buffer object if bufferMode is GL_INTERLEAVED_ATTRIBS or multiple buffer objects if bufferMode is
GL_SEPARATE_ATTRIBS.
In addition to the errors generated by glTransformFeedbackVaryings, the program program will fail to link if:
o The count specified by glTransformFeedbackVaryings is non-zero, but the program object has no vertex or geometry shader.
o Any variable name specified in the varyings array is not declared as an output in the vertex shader (or the geometry shader, if
active).
o Any two entries in the varyings array specify the same varying variable.
o The total number of components to capture in any varying variable in varyings is greater than the constant
GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS and the buffer mode is GL_SEPARATE_ATTRIBS.
o The total number of components to capture is greater than the constant GL_MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS and the buffer
mode is GL_INTERLEAVED_ATTRIBS.
NOTES
glGetTransformFeedbackVarying is available only if the GL version is 3.0 or greater.
ERRORS
GL_INVALID_VALUE is generated if program is not the name of a program object.
GL_INVALID_VALUE is generated if bufferMode is GL_SEPARATE_ATTRIBS and count is greater than the implementation-dependent limit
GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS.
