file1
Code:
12345 aa bbb cccc

76543 pp rrr bbbbb
34567 nn ccc sssss
87654 qq ppp rrrrr

file2
Code:
98765
34567

I need to remove the lines from file1 if the first field contains a value that appears in file2:

output
Code:

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 xdiff 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 or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com- pression 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 or diff 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. Tukaani 2009-07-05 XZDIFF(1)
