This might help you On my CentOS 7 machine, I have a folder which contains 2 files, with names like: , You could use find :
code :
find dir -maxdepth 1 -name 'myapp-nightly__v3.0-SNAPSHOT__b*.zip' -not -name '*lite.zip'
find dir -maxdepth 1 -name 'myapp-nightly__v3.0-SNAPSHOT__b*.zip' -not -name '*lite.zip' -exec unzip {} \;

hop of those help? When the following two lines of code are executed in a bash script, "ls" complains that the files don't exist: , I think it is the order of expansions:
code :
eval ls $dirs
dirs=/content/{dev01,dev02}*

Any of those help You can use the below command to get only the IP address of the device (You need to filter only the IP address part using grep command)
code :
 /sbin/ifconfig -a | grep -i 'inet addr:'
ifconfig eth0 | grep -i 'inet addr:'
#!/bin/sh
# Shows ip address of eth3
/sbin/ifconfig -a | awk '/^eth3/,/^$/' | awk '/inet addr/ { print $2 }' | cut -d: -f2

Does that help On a hunch - your input files have the DOS carriage return line feed combination.
I added that to your file and got the same results you did.
code :
echo $(tr -d "\r\'" < $PROC | awk 'NR==5{print substr($0,index($0,$2))}{print $NF}')
VARS=$(tr -d "\r\'" < $PROC | awk 'NR==5{print substr($0,index($0,$2))}{print $NF}')
read PROCESS STATUS MONITOR PID UPTIME PCPU PMEM <<<$VARS
echo $PROCESS $STATUS $MONITOR $PID $UPTIME $PCPU $PMEM

may help you . Brace expansion turns *.{adb,ads} into two words, *.adb and *.ads. Then, each of those are (independently) glob-expanded. If glob-expansion fails, then the glob is passed unmodified, rather than being deleted. For example, if you had no files with extension ads, you might end up trying to compile f1.adb f2.adb *.ads. Since the last of those doesn't exist, the compiler will complain.
The exact same thing happens with rm *.{ali,o,so} and rm will complain and stop if one of the patterns gets passed through unmodified. But if the command is really rm -f *.{ali,o,so}, then it will execute just fine because the -f flag tells rm to ignore missing files (amongst other things).
code :
compile *.ad[bs]
