I am writing a script to get the multiples of 2 and 3, place them in an 2 arrays, and then show the common integers. So far everything works fine till the comparision. I don't know how to compare them. Here is the code:
Code:
#!/bin/bash
let num1="2"
let num2="3"
[code]...
Is there a way to compare an array in a while conditions?
I have one array that contains the results of some search and if the script has found all the items, then it should stop, so my idea is to have a while loop � la:
Code:
How do I compare the timestamp of two files? I tried this but it doesn't work:
file1time=`stat -c %Y fil1.txt`
file2time=`stat -c %Y file2.txt`
[code]....
I printed both the time stamps, in order and it gives me
1273143480
1254144394
./script.sh: line 13: [1273143480: command not found
So basically if comparision is not working, I guess. Or if there is any other nice way than what I am doing, please let me know.
Edit: There was no space in between if, so changing it to this works:
if [ $file1time -gt $file2time ]
I want to compare 2 name files, for instance. I got the package foo1.tgz and the foo2.tgz. and I want a script in bash that detects foo2 is newer than foo1 and delete foo1. Can it be done for managing collection of slackware packages.
View 2 Replies View RelatedI'm making script for automated compiling of one program which would output builds optimized for many architectures. For clearancy, I do each build in it's own catalogue and list of builds with their respective catalogues would be stored as array. I'm using this guide as reference. It describes making array as naming a variable with additional brackets denoting it's position in array.
In my code, it looks exactly like this:
Code:
mtune[1]="build/mtune/athlon"
mtune[2]="build/mtune/athlon-4"
mtune[3]="build/mtune/athlon-mp"
[code]....
But upon invoking $mtune or any $mtune[x] variable, output is blank, like the variable(s) were never initialized. What am I doing wrong?
I am trying to get PvPGN working... I have installed all the files, the only thing now is that bntrackd wants to use 'logs/bntrackd.log' for it's logfile, but seeing as it's in /usr/sbin, I want it to use /var/log/bntrackd. This is done with 'bntrackd --logfile=/var/log/bntrackd.log' but when I put that in the script it won't process it as a command (instead splitting it and complaining that I don't have --logfile=/var/log/bntrackd.log installed)
/etc/rc.d/pvpgn:
Code:
#!/bin/bash

I would like to combine two arrays and delete duplicates that might occur. I tried to solve it like this:
Code:
combined=( "${results1[@]}" "${results2[@]}" )
printf "${combined[@]}" | sort -n | uniq
Example:
result1 (4 elements):
[Code]....
In my code printf seems to have a problem with elements that have the same letters but a space inbetween. For instance "new foo", "newfoo" are the same for printf
I've got a situation. I'm having GNU bash version 3.00.16(1) on Solaris 10. I need to declare an array say arr1 which will be populated by an output of a command.
declare -a arr1
arr1=( $(/some/command) )
Supposing it will eventually (after executing the command) have element values as -
arr1[0]=1234
arr1[1]=5678
arr1[2]=7890
Now, I need to declare another set of arrays, one for each of the element values above - e.g.
declare -a arr1_1234
declare -a arr1_5678
declare -a arr1_7890
And I also need to populate elements of each of above 3 arrays with output of another command in a loop. So, these arrays will hold values something like -
arr1_1234[0]="abc"
arr1_1234[1]="def"
arr1_1234[2]="ghi"
arr1_5678[0]="jkl"
arr1_5678[1]="mno"
arr1_5678[2]="pqr"
arr1_7890[0]="tuv"
arr1_7890[1]="xyz"
arr1_7890[2]="aab"
I'm able to declare and populate arr1[*]. My question is how do I declare, populate and print the subsequent arrays and their elements?I am feeling rather thick to get this working.
I would like to compare them, in terms of amplitude, length, tempo, ... Which program could basically analyse them giving an sufficient output data
View 2 Replies View RelatedI have a (rather large) database of mp3 track information. I also have several directories of the actual mp3s. I'm trying to write a simple bash script that will check the contents of the directories against what's in the database, and upon finding a file that isn't in the database, do something.
Here's what I have so far:
Code:
The trouble I'm having (in the sample directory of "/mnt/music/B/Beatles, The/" the file "Beatles, The - Taxman.mp3" isn't in the database.) is getting it to actually trigger an error when an entry isn't in the database.
Once triggering on a non-entered file is working, any way to get it to traverse the entire /mnt/music hierarchy?
how to program in bash, an i have a problem, i am trying compare values in between 2 values (from another file), so far my solution is to make a nested for loop, but that causes it to compare every value. Here is a visulization of what i want
file.a 2,3,4,5
file.b
3 5
[code]...
i want the values 2, 3, 4, 5 from file.a to be compared inbetween values 3 5, 6 9,1 2, 4 7 from file.b (var1 is the value im comparing, var2 is the less value, var 3 is the greater value)
for i in $var1
do
for k in $var2
do
[code]....
my problem with the above code is it compares EVERYINNG, not the values inbetween what i want (which is 3 5, 6 9 etc).
Have a bash script which contains a line like this:
if [[ ${array[${last}]} =~ "screenpc.PRODUCTION.*" ]]
which WORKED as expected in bash 4.0.33 and now fails in 4.1.2
Instrumented the script to print the value of the left-hand side and it is exactly what is expected.
As noted above, this has been working fine until we installed Fedora 13 (kernel 2.6.33), and now it fails.
Tried setting shell 'extglob' to On with same results.
Did something change? Are there other shell/bash options that need to be set?this has the whole installation stopped!

View 1 Replies View RelatedSo I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:

Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.
