I need to know if file1 is a subset of file2 i.e all the contents of file1 are present in file2 or not.
Here is how i would do it.
Read line by line file1 and grep every line in file2 in a for loop. any failing grep would means that it is not a subset.
Is there a quicker or easier way... (3 Replies)

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.
