I want to be able to separate data by weeks, and the week is stated in a specific field on every line and would like to know how to use grep, cut, or anything else that's relevant JUST on that field the week is specified in while still being able to save the rest of the data that's being given to me. I need to be able to pipe the information into it via | because that's how the rest of my program needs it to be.
as the output gets processed, it should look something like this
asset.14548.extension 0
asset.40795.extension 0
asset.98745.extension 1
I want to be able to sort those names by their week number while still being able to keep the asset name in my output because the number of times that asset shows up is counted up, but my problem is I can't make my program smart enough to take just the "1" from the week number but smart enough to ignore the "1" located in the asset name.
UPDATE
The closest answer I found was
grep "^.........................$week" ;
That's good, but it relies on every string being the same length. Is there a way I can have it start from the right instead of the left? Because if so then that'd answer my question.
^ tells grep to start checking from the left and . tells grep to ignore whatever's in that space
I found what I was looking for in some documentation. Anchor matches!
grep "$week$" file
would output this if $week was 0
asset.14548.extension 0
asset.40795.extension 0
I couldn't find my exact question or a closely similar question with a simple answer, so hopefully it helps the next person scratching their head on this.

I'm trying to create a flow using Power Automate (which I'm quite new to) that can get the link/URL in an email I receive daily, then download the .csv file that normally a click to the link would do, and then save the file to a given local folder.
An example of the email I get:

I searched in Power Automate Community and found this insightful LINK post & answer almost solved it. However, after following the steps and built the flow, it kept failing at the Compose step.

Error message
Expression used:
substring(body('Html_to_text'),add(indexOf(body('Html_to_text'),'here'),5),sub(indexOf(body('Html_to_text'),'Name'),5))
Seems the expression couldn't really get the URL/Link? I'm not sure and searched but couldn't find any more posts that can help.
Please kindly share all insights on approaches or workarounds that you think may help me solve the problem and truly thanks!

We need to breakdown the bits of the function here which needs 3 bits of info
substring(1 text to search, 2 starting position of the text you want, 3 length of text)
For example, if you were trying to return an unknown number from the text dog 4567 bird
Our function would have 3 parts.
body('Html_to_text'), this bit gets the text we are searching for
add(indexOf(body('Html_to_text'),'dog'),4), this bit finds the position in the text 4 characters after the start of the word dog (3 letters for dog + the space)
sub(sub(indexOf(body('Html_to_text'),'bird'),2)),add(indexOf(body('Html_to_text'),'dog'),4)), I've changed the structure of your code here because this part needs to return the length of the URL, not the ending position. So here, we take the position of the end of the URL (position of the word bird minus two spaces) and subtract it from the position of the start of the URL (position of the word dog + 4 spaces) to get the length.
In your HTML to text output, you need to check what the HTML looks like, and search for a word before the URL starts, and a word after the URL starts, and count the exact amount of spaces to reach the URL. You can then put those words and counts into your code.
More generally, when you have a complicated problem that you need to troubleshoot, you can break it down into steps. For example. Rather than putting that big mess of code into a single block, you can make each chunk of the code in its own compose, and then one final compose to bring them all together - that way when you run it you can see what information each bit is giving out, or where it is failing, and experiment from there to discover what is wrong.
I have 2 files with information that looks like this
File 1
Show1
Show2
Show3
Show4
Show5
File2
Advert1
Advert2
I want to merge these two files into a 3rd textfile so that the output looks like this
Show1
Advert1
Show2
Advert2
Show3
Advert1
Show4
Advert2
Show5
The amount of information can vary, but file two will never have more lines than file 1
I have tried putting the information of the two text files into two different string lists and then reading them alternatively into a third string list via the indexes, I have tried hopping the information across different textiles and string lists and even arrays, but no matter what I try I always end up with an error, most often a list index error...
My latest attempt at this looks like this
For k := 0 to StringlistAdvert.Count - 1 do
Begin
StringListFinal.Add(StringlistShow[k]);
StringListFinal.Add(StringListAdvert[k]);
StringlistAdvert.Delete(k)
End;
I realise that this was a stupid idea as I'm deleting the items in the string list which I later would have to use in the loop again. My other attempts were not much better
This is a relatively simple program compared to others I have coded before yet the solution to this keeps eluding me, it is for a school project so any help would be greatly appreciated
I am using ExifTool to change the camera body serial number to be a unique serial number for each image in a group of images numbering several hundred. The camera body serial number is being used as a second place, in addition to where the serial number for the image is in IPTC, to put the serial number as it takes a little more effort to remove.
The serial number is in the format ###-###-####-#### where the last four digits is the number to increment. The first three groups of digits do not change for each batch I run. I only need to increment that last group of digits.
EXAMPLE
I if I have 100 images in my first batch, they would be numbered:
811-010-5469-0001, 811-010-5469-0002, 811-010-5469-0003 ... 811-010-5469-0100
I can successfully drag a group of images onto my ExifTool Shortcut that has the values
exiftool(-SerialNumber='001-001-0001-0001')
and it will change the Exif SerialNumber Tag on the images, but have not been successful in what to add to this to have it increment for each image.
I have tried variations on the below without success:
exiftool(-SerialNumber+=001-001-0001-0001)
exiftool(-SerialNumber+='001-001-0001-0001')
I realize most likely ExifTool is seeing these as numbers being subtracted in the first line and seeing the second line as a string. I have also tried:
exiftool(-SerialNumber+='1')
exiftool(-SerialNumber+=1)
just to see if I can even get it to increment with a basic, single digit number. This also has not worked.
Maybe this cannot be incremented this way and I need to use ExifTool from the command line. If so, I am learning the command line/powershell (Windows), but am still weak in this area and would appreciate some pointers to get started there if this is the route I need to take. I am not afraid to use the command line, just would need a bit more hand holding then normal for a starting point. I also am learning Linux and could do this project from there but again, not afraid to use it, just would need a bit more hand holding to get it done.
I do program in PHP, JavaScript and other languages so code is not foreign to me. Just experience in writing it for the command-line.
If further clarification is needed, please let me know in the comments.
Your help and guidance is appreciated!
You'll probably have to go to the command line rather than rely upon drag and drop as this command relies upon ExifTool's advance formatting.
Exiftool "-SerialNumber<001-001-0001-${filesequence;$_=sprintf('%04d', $_+1 )}" <FILE/DIR>
If you want to be more general purpose and to use the original serial number in the file, you could use
Exiftool "-SerialNumber<${SerialNumber}-${filesequence;$_=sprintf('%04d', $_+1 )}" <FILE/DIR>
This will just add the file count to the end of the current serial number in the image, though if you have images from multiple cameras in the same directory, that could get messy.
As for using the command line, you just need to rename to remove the commands in the parens and then either move it to someplace in the command line's path or use the full path to ExifTool.
As for clarification on your previous attempts, the += option is used with numbers and with lists. The SerialNumber tag is usually a string, though that could depend upon where it's being written to.
If I understand your question correctly, something like this should work:
1..100 | % {
$sn = '811-010-5469-{0:D4}' -f $_
# apply $sn
}
or like this (if you iterate over files):
$i = 1
Get-ChildItem 'C:\some\folder' -File | % {
$sn = '811-010-5469-{0:D4}' -f $i
# update EXIF data of current file with $sn
$i++
}
I am currently working on a script that processes and combines several different files, and for the one part, it is necessary that I find the difference between two different times in order to determine a "total" amount of time that someone has worked. the times themselves are in the following format
34:18:00,40:26:00,06:08:00
with the first one being start time, second end time, third total time. Although this one is displayed correctly, there are some entries that need to be double checked and corrected (the total time is not correct based on the start/end time). I have found several different solutions in other posts but most of them also include dates and such too (most of them using awk), I am not experienced with awk so am not sure how to go about removing the date portion from those examples. I have also heard that I could convert the times to unix epoch time, but I was just curious if there were any other ways to accomplish this, thanks!
Something like this might help you:
#!/bin/bash
time2seconds() {
a=( ${1//:/ } )
echo $((${a[0]}*3600+${a[1]}*60+${a[2]}))
}
seconds2time() {
printf "%.2d:%.2d:%.2d" $(($1/3600)) $((($1/60)%60)) $(($1%60))
}
IFS=, read start stop difference <<< "34:18:00,40:26:00,06:08:00"
printf "Start=%s\n" "$start"
printf "Stop=%s\n" "$stop"
printf "Difference=%s (given in file: %s)\n" $(seconds2time $(($(time2seconds $stop)-$(time2seconds $start)))) "$difference"
Output is:
Start=34:18:00
Stop=40:26:00
Difference=06:08:00 (given in file: 06:08:00)
Note: there's nothing that checks if the times are in a valid format, I don't know how reliable your data are.
I tried searching for this, but couldn't find much. It seems like something that's probably been asked before (many times?), so I apologize if that's the case.
I was wondering what the fastest way to parse certain parts of a file in Ruby would be. For example, suppose I know the information I want for a particular function is between lines 500 and 600 of, say, a 1000 line file. (obviously this kind of question is geared toward much large files, I'm just using those smaller numbers for the sake of example), since I know it won't be in the first half, is there a quick way of disregarding that information?
Currently I'm using something along the lines of:
while buffer = file_in.gets and file_in.lineno <600
next unless file_in.lineno > 500
if buffer.chomp!.include? some_string
do_func_whatever
end
end
It works, but I just can't help but think it could work better.
I'm very new to Ruby and am interested in learning new ways of doing things in it.
file.lines.drop(500).take(100) # will get you lines 501-600
Generally, you can't avoid reading file from the start until the line you are interested in, as each line can be of different length. The one thing you can avoid, though, is loading whole file into a big array. Just read line by line, counting, and discard them until you reach what you look for. Pretty much like your own example. You can just make it more Rubyish.
PS. the Tin Man's comment made me do some experimenting. While I didn't find any reason why would drop load whole file, there is indeed a problem: drop returns the rest of the file in an array. Here's a way this could be avoided:
file.lines.select.with_index{|l,i| (501..600) === i}
PS2: Doh, above code, while not making a huge array, iterates through the whole file, even the lines below 600. :( Here's a third version:
enum = file.lines
500.times{enum.next} # skip 500
enum.take(100) # take the next 100
or, if you prefer FP:
file.lines.tap{|enum| 500.times{enum.next}}.take(100)
Anyway, the good point of this monologue is that you can learn multiple ways to iterate a file. ;)
I don't know if there is an equivalent way of doing this for lines, but you can use seek or the offset argument on an IO object to "skip" bytes.
See IO#seek, or see IO#open for information on the offset argument.
Sounds like rio might be of help here. It provides you with a lines() method.
You can use IO#readlines, that returns an array with all the lines
IO.readlines(file_in)[500..600].each do |line|
#line is each line in the file (including the last \n)
#stuff
end
or
f = File.new(file_in)
f.readlines[500..600].each do |line|
#line is each line in the file (including the last \n)
#stuff
end
