How to Force command substitution evaluation in bash?
OK, I'm striving to abide by all the rules this time.
Here is a fragment of my windows10/cygwin64/bash script:
"BackupRecords --log" is a program I wrote to return a unique log file name using the current time.
The problem is that I get two different log files. How can I force the evaluation of BUGLOG sooner?
Is it possible with a bash variable to perform multiple substitution strings to one variable?
I have this variable:
echo $clock
TIMEZONE="US/Central"
What I would like to do with bash only it pull out just the "US" part of the variable.. which could be any number of countries.

Hi,

that need to be executed either before ./configure
or after the main 'make' command.

Hello!
I'm writing a shell script using #!/bin/bash instead of #!/bin/sh because of the substitution: ${!variable}, which won't work with sh. My main problem is the following (just a summarized example, the script is much more complex):

Hi all!
I'm writting one script to copy a file in various folders, but there are 2 things to validate. First that the folder where i'll be cpying exists, and second that i have permissions to copy the file in it.
so far i have found the way to validate the folder exists, but when trying to... (6 Replies)
I have one script calling another with a set of strings that includes white space. Script A calls Script B with these input strings: one two "th ree"
Script B pulls apart the arguments correctly:
arg0 = one, arg1 = two, arg2 = "th ree"
if I call it from within Script A like so:... (10 Replies)

Could somebody please explain to me why and how the highlighted line(s) (?) of code puts the "test" evaluation into "result" and then to $enable_static ? Or does not ?
I did comment out the original code and changed it to what I feel is less cryptic , but the "result" is still wrong =... (3 Replies)

SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalEmphasize_S16_S16_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);
mlib_status mlib_SignalEmphasize_S16S_S16S_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);
mlib_status mlib_SignalEmphasize_F32_F32(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);
mlib_status mlib_SignalEmphasize_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);
DESCRIPTION
Each of these functions applies the preemphasizer to one signal packet and updates the filter states.
For monaural signals, the following equation is used:
dst[i] = src[i] - alpha*src[i - 1]
where i = 0, 1, ..., (n - 1); src[-1] = 0.
For stereo signals, the following equation is used:
dst[2*i] = src[2*i] - alpha*src[2*(i - 1)]
dst[2*i + 1] = src[2*i + 1] - alpha*src[2*(i - 1) + 1]
where i = 0, 1, ..., (n - 1); src[-2] = src[-1] = 0.
PARAMETERS
Each of the functions takes the following arguments:
dst Destination signal array.
src Source signal array.
filter Internal filter structure.
n Number of samples in the source signal array.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
