copied!<p>The solutions mentioned above will work for the basics. I don't think they cover multi-line values though. Here is an awk program that will parse Java properties from stdin and produce shell environment variables to stdout:</p> <pre><code>BEGIN { FS="="; print "# BEGIN"; n=""; v=""; c=0; # Not a line continuation. } /^\#/ { # The line is a comment. Breaks line continuation. c=0; next; } /\\$/ && (c==0) && (NF>=2) { # Name value pair with a line continuation... e=index($0,"="); n=substr($0,1,e-1); v=substr($0,e+1,length($0) - e - 1); # Trim off the backslash. c=1; # Line continuation mode. next; } /^[^\\]+\\$/ && (c==1) { # Line continuation. Accumulate the value. v= "" v substr($0,1,length($0)-1); next; } ((c==1) || (NF>=2)) && !/^[^\\]+\\$/ { # End of line continuation, or a single line name/value pair if (c==0) { # Single line name/value pair e=index($0,"="); n=substr($0,1,e-1); v=substr($0,e+1,length($0) - e); } else { # Line continuation mode - last line of the value. c=0; # Turn off line continuation mode. v= "" v $0; } # Make sure the name is a legal shell variable name gsub(/[^A-Za-z0-9_]/,"_",n); # Remove newlines from the value. gsub(/[\n\r]/,"",v); print n "=\"" v "\""; n = ""; v = ""; } END { print "# END"; } </code></pre> <p>As you can see, multi-line values make things more complex. To see the values of the properties in shell, just source in the output:</p> <pre><code>cat myproperties.properties | awk -f readproperties.awk > temp.sh source temp.sh </code></pre> <p>The variables will have '_' in the place of '.', so the property some.property will be some_property in shell.</p> <p>If you have ANT properties files that have property interpolation (e.g. '${foo.bar}') then I recommend using Groovy with AntBuilder.</p> <p>Here is <a href="http://shrubbery.mynetgear.net/c/display/W/Reading+Java-style+Properties+Files+with+Shell" rel="noreferrer">my wiki page on this very topic</a>.</p>
