Hai,
Can you please guide me, to compare the floating point numbers.
Eg.

I need to add leading zeros in a floating point numbers.
The length of the number should be 13 including decimal.
The input number is changing so number of leading zeros is not fix.
For example
input output

I have started using bash but this script which I am working on it, is in c chell. So here is my simple problem:
set x = 0.4124\0.234
echo $x

Same operation in Bash gives me correct result in my terminal. So there is something with my c shell that is causing this behaviour.... (8 Replies)
I have the following code snippet in bash

It works well for most of the cases. However lets say diff is -0.17 and minm is -0.0017. In such a case the comparison seems to fail. Is the correct way to compare a mixture of positive and... (12 Replies)

logprof.conf
LOGPROF.CONF(5) AppArmor LOGPROF.CONF(5)NAME
logprof.conf - configuration file for expert options that modify the behavior of the AppArmor aa-logprof(1) program.
DESCRIPTION
The aa-logprof(1) program can be configured to have certain default behavior by the contents of logprof.conf.
The [qualifiers] section lists specific programs that should have a subset of the full ix/px/ux list when asking what mode to execute it
using.
Since creating a separate profile for /bin/bash is dangerous, we can specify that for /bin/bash, only (I)nherit, (U)nconstrained, and
(D)eny should be allowed options and only those will show up in the prompt when we're asking about adding that to a profile.
Likewise, if someone currently exec's /bin/mount in ix or px mode, things won't work, so we can provide only (U)nconstrained and (D)eny as
options.
And certain apps like grep, awk, sed, cp, and mkdir should always inherit the parent profile rather than having their own profile or
running unconfined, so for them we can specify that only (I)nherit and (D)eny are the allowed options.
Any programs that are not listed in the qualifiers section get the full (I)nherit / (P)rofile / (U)nconstrained / (D)eny option set.
If the user is doing something tricky and wants different behavior, they can tweak or remove the corresponding line in the conf file.
The [defaulthat] section lists changehat-aware programs and what hat aa-logprof(1) will collapse the entries to for that program if the
user specifies that the access should be allowed, but should not have it's own hat.
The [globs] section allows modification of the logprof rule engine with respect to globbing suggestions that the user will be prompted
with.
The format of each line is-- "<perl glob> = <apparmor glob>".
When aa-logprof(1) asks about a specific path, if the perl glob matches the path, it replaces the part of the path that matched with the
corresponding apparmor glob and adds it to the list of globbing suggestions.
Lines starting with # are comments and are ignored.
EXAMPLE
[qualifiers]
# things will very likely be painfully broken if bash has it's own profile
/bin/bash = iu
# mount doesn't work if it's confined
/bin/mount = u
# these helper utilities should inherit the parent profile and
# shouldn't have their own profiles
/bin/awk = i
/bin/grep = i
/bin/sed = i
