Shell Programming and Scripting

Hi,

I am having trouble extracing a string between the quotes.

The OS in solaris 8

I have a directory which has solaris packages and i need to do pkginfo for all and search for uninstalled packages.

#ls -l

drwxr-xr-x 5 root other 512 Apr 14 17:41 SUNWxwplx
drwxr-xr-x 5 root other 512 Apr 14 17:41 SUNWxwpsr
drwxr-xr-x 3 root other 512 Apr 14 17:41 SUNWxwrtl
drwxr-xr-x 3 root other 512 Apr 14 17:41 SUNWxwrtx
drwxr-xr-x 5 root other 512 May 5 18:42 SUNWxwslb
drwxr-xr-x 5 root other 512 May 5 18:42 SUNWxwslx

# ls -l|awk '{print $9}'|xargs pkginfo |grep -i error
ERROR: information for "SUNWxwslb" was not found
ERROR: information for "SUNWxwslx" was not found

I need to extract only SUNWxwslb and SUNWxwslx

I tried using
ls -l|awk '{print $9}'|xargs pkginfo |grep -i error|awk '{print $4}'
and
ls -l|awk '{print $9}'|xargs pkginfo |grep -i error|nawk -F "\"" '{print $1}'

It didnt work.

Can someone point out a method to grep just the package name.

Thanks in advance.

Code:

ls -l|awk '{print $9}'|xargs pkginfo |grep -i error  | nawk -F'"' '{print $2 }'

Hi ,

I tried that before, but iam still getting the same
# ls -l|awk '{print $9}'|xargs pkginfo |grep -i error|nawk -F'"' '{print $2 }'
ERROR: information for "SUNWxwslb" was not found
ERROR: information for "SUNWxwslx" was not found

ERROR: information for "SUNWxwslb" was not found
This is coming from std err, not std. out, so grep is not useful here

Code:

ls -l|awk '{print $9}'|xargs pkginfo 

# this can be shortened to: 

ls -1|xargs pkginfo 2> /dev/null
# note thats a ONE now not an L

Iam sorry that was what iam not looking for, i need to grep for error line and extract the name within quotes.
The command you gave gives excluding the error line.

I'm sure you are checking on each package at a time.
I guess you can try breaking into two steps:
1. Capture the error in variable
2. Run awk on the variable

example:

temp1=`ls -l|awk '{print $9}'|xargs pkginfo |grep -i error`
echo $temp1 | awk -F'"' '{ print $2 }'

This should just echo the package name.

Hi,

I tried and when i gave the first line it just displays the two lines
# temp1=`ls -l|awk '{print $9}'|xargs pkginfo|grep -i error`
ERROR: information for "SUNWxwslb" was not found
ERROR: information for "SUNWxwslx" was not found

# echo $temp1

no output.

Please let me know if something wrong.
