Skip specific line from a text file
显示 更早的评论
I want to read 2041 text files from a folder but mostly files contain 'error found' at the last. How can I skip that line from reading by the code. Picture of the file has been attached.

One approach using fgetl. Another would be to read the entire file in, and just search and throw out that line.
fname = '409.txt'
FID = fopen(fname,'rt');
cntr = 1;
loopEn = 1;
while loopEn
temp = fgetl(FID);
if ~strcmpi(temp,'e r r o r f o u n d') % skip line of error found
FileData{cntr} = temp;
cntr = cntr + 1;
elseif temp == -1
break;
end
end

If you use fopen / textscan / fclose, then you can specify 'commentstyle', 'e r r' . That tells it to skip from 'e r r' to the end of the line when it it is reading in data.
