Search for a string and replace the searched string in the same position in samefile
Hi All,
My requisite is to search for the string "0108"(which is the year and has come in the wrong year format) in a particular column say 4th column in a tab delimited file and then replace it with 2008(the correct year format) in the same position where 0108 was found in the same file..The issue is the last two digits in "0108" tells the year..The file may contain "0109","0110" and so on...i need to replace the correct year depending on the last two digits of the string..How do i go about??please help me....
eg
00000000 0 +00000000.00 2008/12/29 11:06:04 0108/12/29 10:05:37 00521363
i need to change this to
00000000 0 +00000000.00 2008/12/29 11:06:04 2008/12/29 10:05:37 00521363
Thanks in advance!!!
