The cause of your problem is the field contains a "field separator" correctly interpreted by
awk.
man mawk:
Quote:
mawk defines <SPACE> as the regular expression /[ \t\n]+/.
If
report.txt had e.g. <TAB>s as field separators, you'd be lucky - just redefine
awk's
FS variable to be <TAB> only.
If not, you can
- modify the report to use a different column separator.
- have the report replace the spaces in a field with something unambigious (e.g.
_).
- have field 4 treated differently by
awk (if it's always field 4 that could have the problem).
