grep line length limit
Hi Friends,
I am having a funny problem with grep. When I run grep 'expr' file.txt things work fine. But when try to get the line number using the -n option, i.e, grep -n 'expr' file.txt I get a message, "grep: 0652-226 Maximum line length of 2048 exceeded." If the line has more than 2048 characters, then I should have got the error in the first case also. Can somebody please explain why the error is only with the -n option? I am running on AIX 5.1.0.0 Thanks. |

As a guess - the line length is 2045. When grep attempts to write the line number
plus the original line, then the 2048 limit for I/O is exceeded. Edit - I cannot duplicate this problem, the line size limit is not the same. Last edited by jim mcnamara; 10-02-2006 at 11:25 AM.. |

If you have Python in your AIX already: Code:
for linenum, lines in enumerate(open("file.txt")):
if "expr" in lines:
print "Line number: " , linenum

Thanks Jim. That might be the cause.
