I have a comma-delimited CSV file but for some reason our system inserts a new line character at a random location in the file which causes the entire file to break. I can get the number of columns in the file.



How do I solve it with sed and/or perl in a one liner command? I know it's solvable with awk but this is for learning purposes. If using perl, I don't want to use the built-in CSV functions. Is it solvable?? I'm on this problem for several days i can't seem to find a solution :(

  • Find why the newlines are inserted and fix that. That would be the best resolution to the issue.

  • Guess: Newlines are inserted when some internal buffer is full, and written out.

  • For the actual question: Your lines start and end with digits, so removing all newlines not between digit will be a start, but this won't fix the file completely. To detect the other newlines, I guess one would need to add knowledge about how the fields look like.

The awk code will append the next line of input to the current line for as long as there is less than six fields in the current line, or the last field is empty (there is one line that is broken just after the last field separator).

  • thank you for your response! i was trying to make it work with any type of delimiter like so: perl -ne 'chomp;while (tr/quotemeta('"$d2"')/quotemeta('"$d2"')/ < '"$columns"'-1 || /quotemeta('"$d2"')$/) $_ .=readline; chomp print "$_n"' where $d2 for example is a bash variable with value || but it doesnt work :(

Like say by Kusalananda, there is 6 fields on each line, so you can try this gnu sed.



sed -E ':A;h;s/^/,/;s/((,[^,]+)6)(.*)/3/;/./g;N;s/n//;bA;g' infile

  • but unfortunately doesn't work. you didnt test it :p

    Apr 2 at 13:10










  • Is your sed gnu sed? On Openbsd, I must change the code like that : sed -Ee ':A;h;s/^/,/;s/((,[^,]+)6)(.*)/3/;/./g;N;s/n//;bA' -e ';g' infile

The awk code will append the next line of input to the current line for as long as there is less than six fields in the current line, or the last field is empty (there is one line that is broken just after the last field separator).



A Perl workalike:



perl -ne 'chomp;while (tr/,/,/ < 5 || /,$/) $_ .= readline; chomp print "$_n"' file.csv

  • thank you for your response! i was trying to make it work with any type of delimiter like so: perl -ne 'chomp;while (tr/quotemeta('"$d2"')/quotemeta('"$d2"')/ < '"$columns"'-1 || /quotemeta('"$d2"')$/) $_ .=readline; chomp print "$_n"' where $d2 for example is a bash variable with value || but it doesnt work :(

  • @HarryMcKenzie I would use the awk solution for that as it's easier to just change the option-argument for the -F flag.

  • it's ok... it just sucks that our system only has a limited amount of commands and awk is not part of it. and they don't want to install it for some reason so we have to live with sed and perl only.

Like say by Kusalananda, there is 6 fields on each line, so you can try this gnu sed.



sed -E ':A;h;s/^/,/;s/((,[^,]+)6)(.*)/3/;/./g;N;s/n//;bA;g' infile

Displaying single band from multi-band raster using QGIS

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
