How to build a command in a script
Hi All
I am trying to build a script that will take data from a tab separated file and use that to split up a quicktime file. So far the code is as follows
#!/bin/sh
#test parsing of data
#fix excel file output returns
cat $1 | tr "\r" "\n" > $1.fix
printf "\n" >> $1.fix
mv $1.fix $1
FILE=$1
coffee_out=""
coffee_fill="‑splitAt"
coffee_end="‑self‑contained ‑o output.mov $2"
textArray[0]="" # hold text
c=0 # counter
# read whole file in loop
while read c_out line
do
if test $c_out #check there is a value especial for /n for the fix from excel
then
textArray[$c]="$c_out $line" # store line
c=$(expr $c + 1) # increase counter by 1
coffee_out="$coffee_out $coffee_fill $c_out"
fi
done < $FILE
coffee_out="$coffee_out $coffee_end"
echo $coffee_out
splitmovie "$coffee_out"
#The final output should look something like
#splitmovie -splitAt 2 -splitAt 3 -self-contained -o output.mov recode.mov
exit 0
I call the script with two arguments the text file and the quicktime
./split.sh testdata.txt recode.mov
I am a newbie at writing scripts so it could be something really dumb.
I think it is most likely to be me using the wrong way to set the input for splitmovie.
Thanks for your help
Michael

coreadm(2) System Calls Manual coreadm(2)
NAME
coreadm - application core file administration
SYNOPSIS
DESCRIPTION
system call is used to specify the location and pattern for core files produced by abnormally terminating processes. See core(4). This
system call can be used to specify a system wide location for core file placement and/or a process specific pattern.
The structure, is used to specify a system wide or a per-process core file pattern and also specify the current system wide core file set-
tings. is defined in the header
Member Type Member Name Description
char c_pattern The core file pattern.
uint64_t c_flags Core file settings.
Parameters
is expected to be set to It is critical for future backward compatibility that the macro itself be used and not its value.
is the core file pattern. A core file name pattern is a normal file system path name with embedded variables, specified with a leading
character, that are expanded from values in effect when a core file is generated by the operating system. An expanded pattern length
greater than will be truncated to
The possible values are:
c_flags is used to control the system wide core file settings. The flag values can be combination of
Enable/Disable creation of global core files.
Enable/Disable creation of per-process core files.
Enable/Disable creation of global core files for
processes.
Enable/Disable creation of per-process core file for
processes.
If a flag value is not set, then the option is disabled.
For per-process core file setting, c_flags can either be 0 or The former disables core file creation (for that process) and the latter
enables it.
c_pid Should be a (valid) pid of a target process or 0. If c_pid is zero, then the settings are applied to global core file settings.
If c_pid is 1, then the settings are applied to init(1M).
c_in If non-NULL, then the values will be used as new core file settings. If this is NULL, then the c_out parameter is expected to be
non-NULL and system call is used to interrogate the current settings.
c_out If non-NULL, the current settings are returned in this parameter.
RETURN VALUE
Upon successful completion, returns 0. Otherwise, a value of -1 is returned and is set to indicate the error.
ERRORS
fails and does not change the core file settings if
the effective user-ID of the calling process is not a user having appropriate privileges.
The input or output parameter passed to
is an invalid address.
The core file pattern or flags is invalid.
The specified PID is non-zero and does not exist.
EXAMPLES
1. Enable global core file creation using the pattern (core.process-ID.machine-name) in the location
2. Enable per-process core file pattern for the process-ID passed in as argument. The core file will be placed in The pattern is
(core.process-ID.time-stamp).
3. Enable a per-process pattern of core.CUP-ID for all processes in the system (init(1M) core file setting). NOTE: This has to be run
during system startup or reboot the machine after setting this for the settings to take full effect.
