Hi,
i need to copy contents from source to destination with a few conditions, Please helpme out.
Sample input file
Code:
$>cat testfile.txt
/a/b/c/d | /e/f/g/d
(d can be either a file or directory)
my conditions are:
check if destination is valid and if its a file or directory
if its a directory(i.e source is a new file and does not already exist), copy the source(file) to destination
if its a file(there s a file with the same name as source file), take backup and copy the source(file) to destination
if not both, print error msg
Here is what i have tried:
Code:
#!/bin/ksh
src=`cat testfile.txt |awk -F\| '{print $1}' testfile.txt`
dst=`cat testfile.txt |awk -F\| '{print $2}' testfile.txt`
#collect all invalid, or check if source and destination are valid:
if [[ ! -f $src ]];then
echo "Source does not exist"
exit 0
fi
if [[ ! -d $dst && -f $dst ]];then
echo "taking backup of existing $dst and copying new file from $src"
mv $dst $dst.BAK
cp $src $dst
elif [[ -d $dst && ! -f $dst ]];then
echo "copying $src to $dst"
cp $src $dst
else
echo "Destination directory does not exist. Please check..."
exit 0
fi
I have a txt file with several columns and i want to peform an operation on two columns and output it to a new txt file .
file.txt
900.00000 1 1 1
500.00000

I am logged into AIX 6.1 as a root user. I tried copying about 190GB of data to a different folder.
cp -R /u01/data/scope /CY/backup
I got the message:

nalConvertShift_F32S_U8S, mlib_SignalConvertShift_F32S_S8S, mlib_SignalConvertShift_F32S_S16S, mlib_SignalConvertShift_F32S_S32S - data
type convert with shifting
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalConvertShift_F32_U8(mlib_f32 *dst, const mlib_u8 *src, mlib_s32 shift, mlib_s32 n);
mlib_status mlib_SignalConvertShift_F32_S8(mlib_f32 *dst, const mlib_s8 *src, mlib_s32 shift, mlib_s32 n);
mlib_status mlib_SignalConvertShift_F32_S16(mlib_f32 *dst, const mlib_s16 *src, mlib_s32 shift, mlib_s32 n);
mlib_status mlib_SignalConvertShift_F32_S32(mlib_f32 *dst, const mlib_s32 *src, mlib_s32 shift, mlib_s32 n);
mlib_status mlib_SignalConvertShift_F32S_U8S(mlib_f32 *dst, const mlib_u8 *src, mlib_s32 shift, mlib_s32 n);
mlib_status mlib_SignalConvertShift_F32S_S8S(mlib_f32 *dst, const mlib_s8 *src, mlib_s32 shift, mlib_s32 n);
mlib_status mlib_SignalConvertShift_F32S_S16S(mlib_f32 *dst, const mlib_s16 *src, mlib_s32 shift, mlib_s32 n);
mlib_status mlib_SignalConvertShift_F32S_S32S(mlib_f32 *dst, const mlib_s32 *src, mlib_s32 shift, mlib_s32 n);
Each of these functions performs data type convert with shifting.
The following equation is used:
dst[i] = src[i] * 2**shift
See the following table for available variations of this group of data type convert functions.
Type [*] F32 F32S
U8 Y
S8 Y
S16 Y
S32 Y
U8S Y
S8S Y
S16S Y
S32S Y
[*] Each row represents a source data type. Each column represents a destination data type.
Each of the functions takes the following arguments:
dst Destination signal array.
src Source signal array.
shift Left shifting factor.
n Number of samples in the source signal arrays.
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
