Programming :: Run Multiple Bash And Php Scripts From A Bash Script?
Jul 25, 2011
I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?

As I'm starting to learn bash scripting I'm trying to automatize some tasks I usually perform. I have a notification mail I need to send several times a day. It has this structure:
Quote:
Dear user,
blah blah blah blah
You need to contact the following people:
[code]...
To replace "user", I found this:
Code:
read -p "Please enter username: " username
echo "Dear $username,"
Which probe to be very useful with other simple notifications like this. But I don't know how to manage the email addresses as they are usually more than one and could vary from 1 to 10. They should appear one above the other. I found this: "Here is a little work around. The only thing the user needs to do is hit enter without anything else on a line and it will close out"
Code:
#!/usr/bin/ksh
word=a
until [[ $word = "" ]];do
[code]....
I tried to use it and modify for my needs but I failed, I don't realize yet how can I use it. If possible, I would like to use the until loop like the above example just for learning purposes but any other form will be accepted as well.

I have wrote a 1 line command that parses a file, locates the IP Address in the file and then trims the output the way I want it, and then sorts numerically and by uniqueness and then >> appends to output.txt
I can get all the IP's into 1 file "output.txt", but what I am really looking for is some type of way to create a text file, for each IP it finds labeled xxx.xxx.xxx.xxx.txt and also put that ip address into that file..
xxx.xxx.xxx.xxx = the ip address it finds

bash script to give sensible names to a large number of photos. I hope to be able to run a script with an argument which will become the filename followed by a number beginning at 1.
Code:
./file_rename.sh Summer2009_
Summer2009_0001
Summer2009_0002
Summer2009_0003
[Code]....

I have a text string I want to pass as the second arg to a bash shell.
My python line is :
The first arg "gap" works great and the bash shell uses it as $1
I need "fill" passed along as $2 intact
Here is the bash line:
As you can see after the -f it has to be in single quotes and $FILL will complete the single quote
Nothing is getting passed as a second arg from python, I did have the first word at one time but that was 85 tries ago and forgot how I did it!
The bash script complains about an unterminated quote.

For example, I have a text file with data which lists numerical values from two separate individuals
Code:
Person A
100
200
300
400
500
600
700
800
900
1000
1100
1200
Person B
1200
1100
1000
900
800
700
600
500
400
300
200
100
How would I go about reading the values for each Person, then being able to perform mathematical equations for each Person (finding the sum for example)?

I'm trying to write a script that will prompt the user for a username/password, then create that user/password in the right groups on all my machines. I know this is kind of a long way around to avoid a NIS server, but I like making my life more difficult.
This is what I have so far:
Code:
the script has 2 problems: The "if" functions return an error and do not compare the strings successfully. whatever password is entered does get applied properly and the user is unable to login

I have this cool bash script that I worked hard on. But it broke down when it can across files that had non-English characters. Another small problem was getting it to descend into a directory. If it renamed a directory it would not descend into that dir to rename the other files. I would have to run the script twice on the same directory.
Here is the script:
Code:
find -type d -o -regextype egrep -iregex '(.*.ogg|.*.mp3|.*.wav)' | while read s
do
rename -v 'y/A-Z/a-z/' "$s"
done
find -type d -o -regextype egrep -iregex '(.*.ogg|.*.mp3|.*.wav)' | while read n
do
rename -v 's/ /_/g' "$n"
done
A French name like this:
Code:
Chateau De Sable (imagine accents above the letter a)
became this:
Code:
ch303242tea_de_sable
This is not what I wanted.
Why would the script not descend into a directory after it was renamed?

I am trying to think of a logic where my file contains some data I had to read and do some processing. Issue is that file contains data multiple times. For example:
:::::::::::
var1=value1
var2=value2
[code].....
I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.

simple bash code:
Code:
#!/bin/bash
trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c
echo "Press ctrl+c during 5 sec loop"
for ((i=0;i<5;i++)); do
[Code]...
How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

I have a problem with snmp answers being empty or having spaces.
What I already have:
#get all interface indexes (if you wonder - I'm working for a cable company and different cablemodems have different number and types of interfaces):
The problem is the physical address which is sometimes empty and the description which has spaces. So I'm doing 2 snmpgets which is slower than 1 snmpget (sometimes I have up to 18 interfaces).
I'm trying to explain it a bit simpler.
Interface 5 gives me back the following lines:
Ethernet CPE Interface
Now the first line should go into variable ifadm,
2nd line should go into variable ifoper,
3rd line should go into variable ifspeed,
4th line should go into variable iftype,
5th line (which is empty) should go into variable ifphys and finally
6th line (which has spaces) should go into variable ifdescr

I need a script to copy music from a network drive to my local disk. I require the script to auto mount the remote server, then to create the directory path to the mp3's I have a list of all teh songs in the following format, note some have spaces.
\7800SPARE4UsersPublicMusicSample MusicKalimba.mp3 \7800SPARE4UsersPublicMusicSample MusicMaid with the Flaxen Hair.mp \7800SPARE5UsersPublicMusicSample Song Sleep Away.mp3
I can use the following to mount the directory:
mount -t cifs //7800SPARE4/Users /dest-o username=user,password=pass
I'm thinking the best way would be to get the share name 7800SPARE and the grep for all these in the list, then mount it and do a while read LINE However I would need to creat the folders, I am unsure on how to do this. I think I would need to sed the backslashes to forward ones and then use rsync? Then unmount and move on to the next ones, if I can't mount the share It would be nice to log it and skip it.

I would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.

I have a set of files containing data that I need to re-arrange into one single property list.
The files that I have look like this:
Code:
# cat uk
<string>10</string>
<string>11</string>
...
<string>29</string>
[Code]....
So the lines in the files match up but I haven't found a way of reading several files line by line.

I am trying to write a bash script that sources another bash script. Essentially, I need a few lines to check to see if a certain variable is set. If not, I set it manually, and then source a scripts with that variable in the path. I wrote a test script to try it, but for some reason the last line does not work. Here is what I wrote:
#!/bin/sh
source ~setupdir/setup.shrc #just a test, this line works
echo ${#SETUP} # prints 0 if setup is not set, which it isn't
if [ ${#SETUP} -eq 0 ]
then
SETUP="~setupdir"
fi
echo $SETUP # prints ~setupdir
[Code]...

I know that bash can suspend and resume processes, but I am interested in forking and resuming them from different bash instances. So, for example, forking a gui app started from the console so that it will not crash when the terminal is closed. I currently know about screen, which can work, but I was wondering if there was a way similar to Ctrl+Z, bg and fg.

below are the details of my system. I have bash as my current shell, some really common commands aren't working.
Do I need to do a re-installation of bash? Or how do I install a selection of bash commands which I need? (for example a subset of [URL])
Code:
root@sdptfw:~ # uname -a
Linux sdptfw.sdpt.co.za 2.4.36 #1 Tue Jul 22 13:13:24 GMT 2008 i686 i686 i386 GNU/Linux
root@sdptfw:~ # echo $SHELL$
/bin/bash$

I'm trying to create a bash script that will open firefox, evolution, gedit (specific file), etc. For the most part it works, but after it opens evolution or gedit, it pauses execution, until I close that app down.
I don't want to have this done at login, i want to pick and choose when I open them all.

To be honest I cheated and used the .bashrc / .profile files from Ubuntu and all was working fine for a while now and it seems something changed to cause this... any ideas on why I am getting this? I checked my .bashrc and my /etc/profile and it doesn't look like anything is amiss..

I've been using fedora for quite some time now but I've never really written any bash scripts so I'm new to this. Basically what I'm trying to do is create symbolic links of movies that I have organized in this fashion:
Code:
Movies/A
Movies/B
Movies/C
etc.
I basically want to create an "ALL" folder that has links to all the movies in their designated folders. I have created somewhat of a bash script but it does not work.
Code:
#!/bin/bash
cd '/media/Videos/Movies'
for file_name in `ls *`
do
ln -s "$file_name" All/$file_name
done
I don't think its creating the right link to the movies and it is not taking into account the fact that some of the movies have spaces in their names.

I have 5 FTP users that upload files (and subdirectories) in their home directory, i need to mirror theese directories beetween them and with a "master" directory (accessible from a 6th user). Files can contain spaces or others special caracters. All the files are in the same filesystem, and i want to use hard link because i don't want to waste 5 time the space of a single file. I tried with find but i cannot handle spaces in it.
