Question Yesterday in UNIX
Hi,
I want to set a cron job with the yesterday date in a unix server (solaris).
  • I tried TZ=CST+24 date +%Y%m%d but i had TZ=CST+24: not found
  • I tried `perl -mPOSIX -e 'print POSIX::strftime("%Y%m%d",localtime(time() - 86400)) '` it works but I'm not sure that all the clients have perl in their machines.
  • date -v and date -d don't work only -u and -a options work with date in unix:
    date: illegal option -- d
    usage: date [-u] mmddHHMM[[cc]yy][.SS]
    date [-u] [+format]
    date -a [-]sss[.fff]

Anyone has an idea please.
Thanks

What is the poll for?

What shell did you run the TZ one in?

Perl is the only solution that will work dependably everywhere.

Hi.

For some versions of ksh built-in command printf:
Code:
...
A %(date-format)T format can be:
use to treat an argument as a date/time string and to format the
date/time according to the date-format as defined for the
date(1) command.
...
man ksh, section printf

So
Code:
printf "%(%Y-%m-%d)T\n" "yesterday"

would print ( for today = Fri Feb 13 12:01:29 CST 2015 )
Code:
2015-02-12

For ksh 93s+

Best wishes ... cheers, drl

PS:
Code:
TZ=CST+24 date +%Y%m%d

produced
Code:
20150212

in a system like:
Code:
OS, ker|rel, machine: SunOS, 5.10, i86pc
Distribution        : Solaris 10 10/08 s10x_u6wos_07b X86

for both ksh and bash.

And for csh / tcsh
Code:
setenv TZ CST+24 ; date +%Y%m%d

produces
Code:
20150212

For GNU date, what's wrong with:
Code:
date -d 'yesterday'

with you format also specified? If you lack GNU date, get a copy at a trusted source. Or, you can search here for my time utility tm2tm.c, which does the same sort of things.

Agreed. Removed it.

Given up on Solaris, but is there no GNU-equivalent date command in /usr/sfw or /usr/xpg? ?

Hi, Scott.

My recollection is that I tried to port GNU coreutils to get GNU date for Solaris. I was not successful.

It might be useful for the community here to have someone (with more expertise that I have) do a port. Judging from the posts here, I would say for Solaris and AIX, possibly HPUX.

I never found anything in sfw in Solaris to handle date arithmetic, but it's possible I missed something -- it was years before I stumbled on sfw Smilie I figured if the Sun/Oracle folks couldn't do the port, then it was probably difficult, or required a lot of extra work. The stuff in sfw seemed mostly like stand-alone items, e.g. ggrep ... cheers, drl

Seems like sunfreeware went commercial, but SPARC Solaris 10 code is here: Freeware List for SPARC and Solaris 10
Code:
coreutils-8.11-sol10-sparc-local.gz GNU Coreutils are a set of basic file, shell, and text manipulation utilities for the GNU operating system that are expected to exist on every operating system. Previously, they were offered as three individual distributions: fileutils, shellutils, and textutils - installs in /usr/local. Dependencies: libiconv, libintl, gmp, and to obtain /usr/local/lib/libgcc_s.so.1 you will need to have installed libgcc-3.4.6 or gcc-3.4.6 or higher.
The programs included are
