SED command works in terminal, but not Applescript
The following command works perfectly in Terminal, but not in Applescript. (Returns "unknown token" error for square brackets.)
(new to site. sorry.)
I have an Applescript that is designed to find and remove any square-bracketed text, including the square brackets.
I ran the following code from Terminal and it does exactly what I want it to do.
However, when I attempt to use this code inside an Applescript, it errors at the square brackets.
I am looking for syntax that will resolve this.

Hi all .... vexing problem here ...
I am using sed to replace some special characters in a .txt file:
sed -e 's/_<ED>_/_355_/g;s/_<F3>_/_363_/g;s/_<E1>_/_341_/g' filename.txt
This command replaces <ED> with í , <F3> with ó and <E1> with á.
When I run the command to standard output, it works... (1 Reply)
What I want my script to do is to run a command in Terminal and close that same Terminal window when the process is complete.
Of course I could ad a delay of 6 seconds to complete the process, but it may not be enough every time.
To simplify my question, this is what I want to achieve.... (9 Replies)
Hi, I have a question.
I define a function using sed command:
replace()
{
searchterm=$1
replaceterm=$2
sed -e "s/$searchterm/$replaceterm/ig" $3 > $WORK'tempfile.tmp'
mv $WORK'tempfile.tmp' $3
}
Then I call
replace 'test = 0' 'test = 1' $myfileThis code works well in... (1 Reply)

Hi,
I am a bit confused ,why would a sed command work fine outside of ksh script but not inside.
e.g
I want to replace all the characters which end with a value and have space at end of it.
so my command for it is :
sed -i "s/$SEPARATOR /$SEPARATOR/g" file_name
This is working fine in... (8 Replies)

pnmpsnr
pnmpsnr(1) General Commands Manual pnmpsnr(1)NAME
pnmpsnr - compute the difference between two images (the PSNR)
SYNOPSIS
pnmpsnr [pnmfile1] [pnmfile2]
DESCRIPTION
Reads two PBM, PGM, or PPM files, or PAM equivalents, as input. Prints the peak signal-to-noise ratio (PSNR) difference between the two
images. This metric is typically used in image compression papers to rate the distortion between original and decoded image.
If the inputs are PBM or PGM, pnmpsnr prints the PSNR of the luminance only. Otherwise, it prints the separate PSNRs of the luminance, and
chrominance (Cb and Cr) components of the colors.
The PSNR of a given component is the ratio of the mean square difference of the component for the two images to the maximum mean square
difference that can exist betwee any two images. It is expressed as a decibel value.
The mean square difference of a component for two images is the mean square difference of the component value, comparing each pixel with
the pixel in the same position of the other image. For the purposes of this computation, components are normalized to the scale [0..1].
The maximum mean square difference is identically 1.
So the higher the PSNR, the closer the images are. A luminance PSNR of 20 means the mean square difference of the luminances of the pixels
is 100 times less than the maximum possible difference, i.e. 0.01.
