Operating Systems Solaris Convert string (YYYYMMDD) format to date in Sun OS Post 303015094 by Chubler_XL on Tuesday 27th of March 2018 04:32:27 PM

You could do this with perl eg:

Code:
#!/bin/perl
use POSIX;
use Time::Local;

my ($yyyy, $mm, $dd) = (
   $ARGV[0] =~ /([0-9]{4}) ([0-9]{2}) ([0-9]{2})/x
);

eval {
   print strftime("%a\n", localtime(timelocal(0,0,0,$dd,$mm - 1,$yyyy)))
};
print "ERROR: Format is YYYYMMDD\n" if $@;


Or, for a bit if fun, you could use cal and nawk like this:

Code:
Y=${1%????}
M=${1#????}
D=${M#??}
M=${M%??}
cal $M $Y | nawk '/^[A-Z]/ { split($0, dayname, " ") } dayname[1] && match($0, wd) { print dayname[int((RSTART+2)/3)] ; exit }' wd=$D

Assumption here is that each day takes three vertical text columns like this so when we find a day in the cal output we can calculate the heading it is under:

Code:
     March 2018     
Su Mo Tu We Th Fr Sa
             1  2  3 
 4  5  6  7  8  9 10 
11 12 13 14 15 16 17 
18 19 20 21 22 23 24 
25 26 27 28 29 30 31

Environment Variables determines the locale to use for the locale categories when both and the corresponding environment variable (beginning with do not specify a locale. If is not set or is set to the empty string, a default of "C" (see lang(5)) is used. determines the locale for interpretation of sequences of bytes of text data as characters (e.g., single- verses multibyte characters in arguments and input files). determines the format and contents of the calendar. determines the timezone used to calculate the value of the current month. If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. EXAMPLES
The command: prints the calendar for September, 1850 on the screen as follows: However, for UNIX Standard (see standards(5)), the output looks like below: WARNINGS
