Remove the date from a text file

[Dominal]

Hi!

I have a text file with many lines and each line contains today's date in the format cyyddd (century,year,day of the year) in different position. How to chop all the date using shell script (sh/csh)?

Thanks!

One way is sed:

sed 's/003063//g' data.file

Regards,

Ed

Or get today as a variable :
#!/bin/ksh
das=`date +%Y%m%d`
sed 's/'$das'//g' testfile > newfile

Thanks Olded and Dickiebird!

However, the +%Y%m%d only shows the date in the format 20030305 instead of 003064(0->century, 03->year, 064->day 64 of year 2003). How can we transform into the day of the year?

 

[dickiebird]

Use %j ( do a lookup in the manual for date)
and use cut to trim the returned string:
das=`date +%Y%m%j|cut -c2-9`
