Hi Guys,
My first post..:)
Right...I want to move existing files (with some date in their name) currently in $mainftp, to $mainfolder/$foldate/system1.
I'd like to be able to increment date in the for loop? Is this possible or should I use a different technique.

I need to increment a date value through shell script.
Input value consist of start date and end date in DATE format of unix.
For eg.
I need increment a date value of 1/1/09 to 31/12/09 i.e for a whole yr.
The output must look like
1/1/09

Hi all,
I need to increment date at run time.
Example:
I need to write a shell script with two parameters.
1. country code like (US,UK, IND.....)
2. Date range from_date to to_date (20070101 to 20070331)
I need to run shell script like this
country_info.sh US 20070101 20070331

hey guys,
I need to incerement the date variable for instance
echo `date '+%F %H:%M:00'`
this produces
2014-08-02 20:05:00
-I will grant this to : $Datehour and need to assign 1 hr from now to $Datelasthour
-the script time will be used to talk to DB system information.

hi all,
i would like to increment the date variable i am using
for((i=20190731;i<=20190801;i++))
do
done
after 20190731 it should be 20190801 but this taking as 20190732,20190733....
kindly help me to solve this (3 Replies)

error::sdt
ERROR::SDT(7stap)ERROR::SDT(7stap)NAME
error::sdt - <sys/sdt.h> marker failures
DESCRIPTION
Systemtap's <sys/sdt.h> probes are modeled after the dtrace USDT API, but are implemented differently. They leave a only a NOP instruction
in the userspace program's text segment, and add an ELF note to the binary with metadata. This metadata describes the marker's name and
parameters. This encoding is designed to be parseable by multiple tools (not just systemtap: GDB, the GNU Debugger, also contains sup-
port). These allow the tools to find parameters and their types, wherever they happen to reside, even without DWARF debuginfo.
The reason finding parameters is tricky is because the STAP_PROBE / DTRACE_PROBE markers store an assembly language expression for each op-
erand, as a result of use of gcc inline-assembly directives. The compiler is given a broad gcc operand constraint string ("nor") for the
operands, which usually works well. Usually, it does not force the compiler to load the parameters into or out of registers, which would
slow down an instrumented program. However, some instrumentation sites with some parameters do not work well with the default "nor" con-
straint.
unresolveable at run-time
GCC may emit strings that an assembler could resolve (from the context of compiling the original program), but a run-time tool can-
not. For example, the operand string might refer to a label of a local symbol that is not emitted into the ELF object file at all,
which leaves no trace for the run-time. Reference to such parameters from within systemtap can result in "SDT asm not understood"
errors.
too complicated expression
GCC might synthesize very complicated assembly addressing modes from complex C data types / pointer expressions. systemtap or gdb
may not be able to parse some valid but complicated expressions. Reference to such parameters from within systemtap can result in
"SDT asm not understood" errors.
overly restrictive constraint
GCC might not be able to even compile the original program with the default "nor" constraint due to shortage of registers or other
reasons. A compile-time gcc error such as "asm operand has impossible constraints" may result.
There are two general workarounds to this family of problems.
change the constraints
While compiling the original instrumented program, set the STAP_SDT_ARG_CONSTRAINT macro to different constraint strings. See the
GCC manual about various options. For example, on many machine architectures, "r" forces operands into registers, and "g" leaves
operands essentially unconstrained.
revert to debuginfo
As long as the instrumented program compiles, it may be fine simply to keep using <sys/sdt.h> but eschew extraction of a few indi-
vidual parameters. In the worst case, disable <sys/sdt.h> macros entirely to eschew the compiled-in instrumentation. If DWARF
debuginfo was generated and preserved, a systemtap script could refer to the underlying source context variables instead of the
positional STAP_PROBE parameters.
