Hi.

You can do it with sed:
Code:
$ cat file1
wwwe 1 ioie ewew yyy uuu 88
erehrlk 4 ihoiwhe lkjhassad lkhsad yyy mmm 45
jhash lhasdhs lkhsdkjsn ouiyrshroi oihoihswodnw oiyhewe yyy ggg 77

$ sed "s/yyy.*//" file1
wwwe 1 ioie ewew 
erehrlk 4 ihoiwhe lkjhassad lkhsad 
jhash lhasdhs lkhsdkjsn ouiyrshroi oihoihswodnw oiyhewe 

# I suppose more accurate would be
sed "s/\wyyy.*//" file1
# or
sed "s/  *yyy.*//" file1

xzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and xzdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp(1) or diff(1).  If only one file is specified, then the files compared are file1 (which must have a suffix of  a  supported
       compression format) and file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp(1) or diff(1) is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
