Linux command :

write it into other new outputfile.txt

sed   's/\///g' yourfile.txt >outputfie.txt

or

overwrite the same file yourfile.txt  after

 sed  -i   's/\///g' yourfile.txt

it should works

 tr "//\r" "\r" <yourfile.txt >outout.txt

it will only replace  the last "/" at the end of line

@xeroxzerox: in infile.backup you have your original text. Including all the lines that end in "/".
The cleaned lines are in infile.

HI duncanb7,
 your command output is
root@LEN-A70-198:/home/#  tr "//\r" "\r" 2013-11-28_ad.log > /home/outout.txt
tr: extra operand `2013-11-28_ad.log'
Try `tr --help' for more information.

Hi DanCraciun,
i do it but it only store 724 lines in orignal file & after, it send all lines in backup file include without / lines.
Why original file contain only 724 lines.if sed read all (30000 lines) then it store all lines.

What sed -i.backup does is:
1. copy 2013-11-28_ad.log as 2013-11-28_ad.log.backup
2. delete lines from 2013-11-28_ad.log as per the regular expressions

If you do NOT want your original file modified, but instead copy the lines that don't end in "/" in another file, try this:

sed -n '/\/$/!p' ./2013-11-28_ad.log > 2013-11-28_ad.log.new

please also convert  dos to unix format  that make sure yourfile in unix format  by

 dos2unix  yourfile.txt output.txt  OR  on vi editor by :set fileformat=unix and save it

this is my final , please try it , it works at my side


sed 's/\/$//g' yourfile.txt>output.txt

Or  overwrite file

 sed -i 's/\/$//g' yourfile.txt
