Use while loop to read file and use ${file} for both filename input into awk and as string to print
I have files named with different prefixes. From each I want to extract the first line containing a specific string, and then print that line along with the prefix.
I've tried to do this with a while loop, but instead of printing the prefix I print the first line of the file twice.
Files:
Here's what I've tried:
But, again, instead of printing the prefix as the first column, it prints the first line of the file.
I'm having problems since few days ago, and i'm not able to make it works with a simple awk+grep script (or other way to do this).
For example, i have a input file1.txt:
cat inputfile1.txt
218299910417
1172051195
1172070231
1172073514

Hi All,
Do we know how to read input file within awk script and send output toanother log file. All this needs to be in awk script, not in command line. I am running this awk through crontab.

gappletviewer
GAPPLETVIEWER(1) GNU GAPPLETVIEWER(1)NAME
gappletviewer - Load and runs an applet
SYNOPSIS
appletviewer [OPTION]... URL...
appletviewer [OPTION]... -code CODE
appletviewer [OPTION]... -plugin INPUT,OUTPUT
DESCRIPTION
The appletviewer tool loads and runs an applet.
Use the first form to test applets specified by tag. The URL should resolve to an HTML document from which the appletviewer will extract
applet tags. The APPLET, EMBED and OBJECT tags are supported. If a given document contains multiple applet tags, all the applets will be
loaded, with each applet appearing in its own window. Likewise, when multiple URLs are specified, each applet tag instance is given its
own window. If a given document contains no recognized tags the appletviewer does nothing.
appletviewer http://www.gnu.org/software/classpath/
Use the second form to test an applet in development. This form allows applet tag attributes to be supplied on the command line. Only one
applet may be specified using the -code option. The -code option overrides the URL form -- any URLs specified will be ignored.
appletviewer -code Test.class -param datafile,data.txt
gcjwebplugin uses the third form to communicate with the appletviewer through named pipes.

PLUGIN OPTION
-plugin INPUT,OUTPUT
gcjwebplugin uses the -plugin option to specify the named pipe the appletviewer should use for receiving commands (INPUT) and the one
it should use for sending commands to gcjwebplugin (OUTPUT).
DEBUGGING OPTION
-verbose
Use the -verbose option to have the appletviewer print debugging messages.
STANDARD OPTIONS
-help
