Hi, I want to remove last two spaces from the last record only in a file in UNIX. Note that i dont want to remove from all records. I have a file like this: 100;aaa;N$$ 101;bbb;N$$ 102;ccc;N$$ Here $ represent Spaces. I want the output like this: 100;aaa;N$$ 101;bbb;N$$ 102;ccc;N Please tell me the command in unix to do that. Thanks in advance Regards Atul

Hi, I got the solution myself #get last record tail -2 $1/Atul_rel.txt > $1/tmp #remove space from last record sed 's/[ \t]*$//' $1/tmp > $1/tmp1 #delete last record from main file sed '$d' $1/Atul_rel.txt > $1/test_rel_1 #append last record to main file cat $1/test_rel_1 $1/tmp1 > $1/REL_File_test.txt #delete last record from main file sed '$d' $1/REL_File_test.txt > $1/REL_File.txt rm $1/tmp $1/tmp1 $1/test_rel_1 $1/REL_File_test.txt

Two different solutions using sed's line addressing: # on last line, delete last 2 spaces sed '$s/ $//' datafile.txt # on the last line, delete all trailing spaces sed '$s/[ ]*$//' datafile.txt
