Below I try to control that the input is good an IP :
Code:
#!/bin/bash
cp /home/scripts/choice_interfaces.txt /home/scripts/interfaces.txt
chmod 644 /home/scripts/interfaces.txt
echo -e "Please enter the network informations into the /etc/network/interfaces file, complete them below :\n"
sed -n '1,10p' choice_interfaces.txt
printf "address " ; read -r address
if [[ $address =~ ^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]]; then
printf "network " ; read -r network
printf "netmask " ; read -r netmask
printf "broadcast " ; read -r broadcast
printf "gateway " ; read -r gateway
else
echo "$address doesn't correct"
fi
sed -i '12s/$/\n address '$address'/' interfaces.txt
sed -i '13s/$/\n network '$network'/' interfaces.txt
sed -i '14s/$/\n netmask '$netmask'/' interfaces.txt
sed -i '15s/$/\n broadcast '$broadcast'/' interfaces.txt
sed -i '16s/$/\n gateway '$gateway'/' interfaces.txt
mv /home/scripts/interfaces.txt /etc/network/interfaces
I try a loop.. :
Code:
printf "address " ; read -r address
while [[ $address =~ ^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]]; do
printf "address " ; read -r address
done
I wanted that the user be invited to type until his input is good
printf "network " ; read -r network
printf "netmask " ; read -r netmask
printf "broadcast " ; read -r broadcast
printf "gateway " ; read -r gateway
I do an example that I will wish, because I row.. :
Code:
#!/bin/bash
cp /home/scripts/choice_interfaces.txt /home/scripts/interfaces.txt
chmod 644 /home/scripts/interfaces.txt
echo -e "Please enter the network informations into the /etc/network/interfaces file, complete them below :\n"
sed -n '1,10p' choice_interfaces.txt
while[[ $address $network $netmask $broadcast $gateway =~ ^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]] || [[-z $address $network $netmask $broadcast $gateway]]; do (I found it on google to test if the input is empty but Its not working)
printf "address " ; read -r address
printf "network " ; read -r network
printf "netmask " ; read -r netmask
printf "broadcast " ; read -r broadcast
printf "gateway " ; read -r gateway
done
sed -i '12s/$/\n address '$address'/' interfaces.txt
sed -i '13s/$/\n network '$network'/' interfaces.txt
sed -i '14s/$/\n netmask '$netmask'/' interfaces.txt
sed -i '15s/$/\n broadcast '$broadcast'/' interfaces.txt
sed -i '16s/$/\n gateway '$gateway'/' interfaces.txt
#mv /home/scripts/interfaces.txt /etc/network/interfaces1
Wow I'm so zoned out I don't even know if I posted this question up already (I couldn't find it in my book marks or in "yesterday's" post).

I have the following script and at the moment it doesn't work and I believe the problem is that I am using a while loop within a while loop. When I run the script using sh -x I can see... (6 Replies)

Hi, I hope the title does not scare people to look into this thread but it describes roughly what I'm trying to do. I need a solution in PHP.

Firstly, I would like to apologize if this is not the appropriate sub-forum to post about GNU/BSD makefile scripting. Though my code is in C++, because I am focusing on the makefile I thought it would go better in shell scripting. Please correct me if I am wrong.
Secondly, I am not interested in... (0 Replies)

I am using this code:

However, in the second loop instead of GGGGGG|TTTTT, I should use AAAAAA|CCCCCC.
For third loop CCAAAA|CCCCAA, so on and so forth. Is there any way to accomplish this without writing... (20 Replies)

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
