I downloaded a 203775480 bytes (~200 MiB, exact size is important for a later error) JSON file which has all entries all on one line. Needless to say, my text editor (ViM) cannot efficiently navigate in it and I'm not able to understand anything from it. I'd like to prettify it. I tried to use cat file.json | jq '.', jq '.' file.json, cat file.json | python -m json.tool but none worked. The former two commands print nothing on stdout while the latter says Expecting object: line 1 column 203775480 (char 203775479).
I guess it's broken somewhere near the end, but of course I cannot understand where as I cannot even navigate it.
Have you got some other idea for prettifying it? (I've also tried gg=G in ViM: it did not work).
I found that the file was indeed broken: I accidentally noticed a ']' at the beginning of the file so I struggled to go to the end of the file and added a ']' at the end (it took me maybe 5 minutes).
Then I've rerun cat file.json | python -m json.tool and it worked like a charm.

I have a csv file with this structure:
123;rr;2;RRyO, chess mobil;pio;25.766;1;0;24353;21.6;;S
1243;rho;9;RpO, chess yext cat;downpio;67.98;1;0;237753;25.34600;;S
I want all the numbers of a specific column to have only 2 decimals (adding or removing decimals).
With this output
123;rr;2;RRyO, chess mobil;pio;25.766;1;0;24353;21.60;;S
1243;rho;9;RpO, chess yext cat;downpio;67.98;1;0;237753;25.34;;S
I have tried this, but doesnt work
sed 's/[[:digit:]]*\.//g' data.csv
Any idea?
Maybe a script is needed?
Perl to the rescue!
perl -F\; -ne '$F[9] = sprintf "%.2f", $F[9]; print join ";", #F' -- file.csv
Note that it will set the value on line 2 to 25.35, not 25.34, as that's how %f rounds 25.346.
You can use
$F[9] = sprintf "%.2f", int($F[9] * 100) / 100
to get the output you want.
In sed, you need to distinguish the two cases: there's only a single deciaml, or there're more than two.
sed -E 's/(;[0-9]+)\.([0-9])(;[^;]*;[^;]*)$/\1.\20\3/' \
-E 's/(;[0-9]+)\.([0-9]{2})[0-9]+(;[^;]*;[^;]*)$/\1.\2\3/'
$ awk '{$(NF-2) = sprintf( "%0.2f", $(NF-2))}1' FS=\; OFS=\; input
123;rr;2;RRyO, chess mobil;pio;25.766;1;0;24353;21.60;;S
1243;rho;9;RpO, chess yext cat;downpio;67.98;1;0;237753;25.35;;S
This might work for you (GNU sed):
sed -E 's/^/;/;s/;[0-9]*\.[0-9]*/&00/g;s/(;[0-9]*\.[0-9]{2})[^;]*/\1/g;s/.//' file
Prepend a csv delimiter to the start of the line so that global regexp will match successfully.
If a field looks like a decimal; append two 0's.
If a field looks like a decimal; shorten it to two decimal places.
Remove the introduced csv delimiter.
N.B. This does not account for rounding.
If rounding is required perhaps:
sed -E 's/^/;/;s/;([0-9]*\.[0-9]*)/$(printf ";%.2f" \1)/g;s/.(.*)/echo "\1"/e' file

I would like to give me your advice about using cadence orcad
so I can run sequentially cir or net(netlist) files with pspice.exe in cmd of my pc.
I use tcl/tk language.I have tried a few things without any results.
I want to make something similar to this one:
set top {C:\Users\file1.net C:\Users\file2.net};
foreach a $top
{exec D:\\tools\\bin\\pspice.exe -r $a}
There are two problems in your code.
The first problem is that \f is an escape character sequence in lists (for “go down one line”, IIRC; point is you don't want that interpretation). The second problem is that you've got your brace placement wrong in your foreach.
The first problem is best addressed by using / instead of \, and then using file nativename on the value fed to the OS. (You have to do that manually for argument to executables in expr; Tcl can't fix that for you entirely automatically.) The second problem is just a syntax error.
Try this:
set top {C:/Users/file1.net C:/Users/file2.net}
set pspice D:/tools/bin/pspice.exe
foreach a $top {
# Tcl knows how to convert executable names for you; not the other args though
exec $pspice -r [file nativename $a]
}
On Windows you may also try:
package require twapi
set top {C:/Users/file1.net C:/Users/file2.net}
foreach a $top {
twapi::shell_execute -path [file nativename $a]
}
This will work only if *.net files are already associated with PSpice application.
The code above rely on TWAPI extension (if you have it) and its shell_execute function, to open a document just like double-click works.
It's always a good idea to avoid backslashes in your code (no need to put it twice to escape them), file nativename will do the job for you.

Could you please try following (written and tested with provided samples).
awk -v s1="\",\"" '{val=(val?val s1:"")$0} END{print val}' Input_file
Explanation: Adding a detailed level of explanation for above code.
awk -v s1="\",\"" ' ##Starting awk program here and creating variable s1 whose value is ","
{ ##Starting this code main BLOCK from here.
val=(val?val s1:"")$0 ##Creating variable val whose value is keep concatenating to its own value.
} ##Closing this program main BLOCK here.
END{ ##Starting END block of this program from here.
print val ##Printing variable val here.
} ##Closing this program END block here.
' Input_file ##Mentioning Input_file name here.
To save output into shell variable and read values from shell variable try like (where var is your shell variable having values, you could name it as per your wish):
var=$(echo "$var" | awk -v s1="\",\"" '{val=(val?val s1:"")$0} END{print val}'); echo "$var"
I would change all occurrences, then change the first one back:
sed -e 's/https/", "https/g' -e 's/", "https/https/'
(Your examples don't quite match your description of the goal, so I can't test this solution but I think it's at least roughly correct.)
awk 'BEGIN{ORS=','}1' file
This will give you an extra comma at the end
awk '{printf (FNR==1?"":",")"%s", $0}' file
This will not

I'm trying to convert a large JSON file to a CSV format. (I've just learned how to use jq so I'm still a beginner).
I've successfully managed to convert most of the data, however, I'm stuck at an array. Every JSON object in the file is supposed to be converted to a single CSV row, and I can't get that to work.
I've been trying to help myself with an existing answer:
Convert/Export JSON to CSV
But the problem is that this method writes a row for each item in the array, needlessly repeating information.
I am using the same type of command as the above answer, the only difference being the name of the columns, but the array blocks...
For instance, I could have a JSON file resembling:
{resources:[
{"id":"001","name"="Robert","items":[
{"label":"00A","name":"Pen"},
{"label":"00B","name":"Paper"}],
{"id":"002","name"="Bruce","items":[
{"label":"00A","name":"Pen"},
{"label":"00B","name":"Computer"},
{"label":"00C","name":"Headphones"}]
]
}
That I would like to become:
001,Robert,Pen,Paper,
002,Bruce,Pen,Computer,Headphones
I only need the name columns of the array
For the moment, the result is:
001,Robert,Pen
001,Robert,Paper
002,Bruce,Pen,
002,Bruce,Computer
002,Bruce,Headphones
The problem is the actual array is about 30 items long for each JSON object, making it impossible to use this way.
$ jq -r '.resources[] | [.id,.name,.items[].name] | #csv' < /tmp/b.json
"001","Robert","Pen","Paper"
"002","Bruce","Pen","Computer","Headphones"
You can use awk to fix up your current output file.
awk -F, '{a[$1","$2]=a[$1","$2]","$3}; END{for (v in a) print v a[v]}' in.txt | sort >out.txt
Input:
001,Robert,Pen
001,Robert,Paper
002,Bruce,Pen,
002,Bruce,Computer
002,Bruce,Headphones
Output:
001,Robert,Pen,Paper
002,Bruce,Pen,Computer,Headphones

I am trying to make a batch file that asks questions then uses the variables to make a html file. Is there a way to replace characters WITHIN COMMAND LINE with the stored variables?
I am making my batch file have a very short HTML template with the basics (font-size, colour) and I want the user to be able to choose the font size and colour then have the batch file output the completed template as a HTML. Heres a bit of my bat file. How do I replace the %%% in a cmd environment?
<html><body>
Hello
</span>NAME HERE
<p <span style='font-size:%%%pt'>
<span style='color:%%%'>
</span></p></body></html>"
You have to escape all <> with a caret in a batch, otherwise this is trivial and should be no problem - even for beginners.
