chmod +x file changes a file from rw-r--r-- to rwxr-x-r-x but really I only wanted rwx-r--r-- is this possible?

How to add +x just for user with chmod?

To change only the permission for the current user, you can use:
chmod u+x <file>
Where u=user, g=group, o=others.
If you want to enforce the permissions you mentioned, this would be the ideal:
chmod u=rwx,go=r file
Optionally, you can do the same using the octal notation, as follows:
chmod 744 <file>
This will set rwx (the 7) for user, and r (the 4's) for group and others.

Try running chmod u=rwx,go=r file.
In my case, that gives the permissions as rwx-r--r--, which I think is what you meant.

You'd be much more likely to get a good answer on Unix/Linux SE

chmod u+x file. u=user, g=group, o=others. – jweyrich – 2014-03-11T01:15:04.6771@jweyrich put that as an answer -- that's more elegant and better than my way... – evamvid – 2014-03-11T01:17:48.167
1The question probably has dozens of duplicates, but I posted it as an answer anyway. Glad it helped. – jweyrich – 2014-03-11T01:38:26.643
2@evamvid this question is perfectly on topic here, no reason to suggest the OP take it to [unix.se]. And I say that as a regular of both sites. – terdon – 2014-03-11T05:52:59.623
nicely put @terdon :) – GMasucci – 2014-03-11T11:34:51.073
@terdon also speaking as a regular of both sites, I didn't mean that this question was off-topic on this site; I was just trying to point out that, in general, Linux-specific questions will get better and/or more complete answers on U+L SE
– evamvid – 2014-03-11T20:19:44.797@evamvid not true, U&L is great for the more obscure, in-depth answers, this is an elementary question about the basic options of a standard command. U&L would not find it very interesting and would likely ignore it. This is a better home for this type of question. – terdon – 2014-03-12T00:35:00.557
