Top Forums UNIX for Dummies Questions & Answers Question on using a variable in KSH Post 302451883 by methyl on Wednesday 8th of September 2010 11:04:29 AM

The problem is that underscore is a valid character in a variable name.
The shell is substituting $NAME_test not $NAME .
Surrounding the variable name with braces is the solution and many scripters do this routinely.
Following on from radolouv is is also conventional to put double quotes round strings whether or not it is mandatory.

Code:
NAME="hello"
cp "${NAME}_test.tgz" "/tmp/${NAME}_test.tgz"

BOOTCHART(1)						      General Commands Manual						      BOOTCHART(1)

NAME
bootchart - render a chart from the statistical data recorded with bootchartd SYNOPSIS
bootchart [-f|--format FORMAT] [-n|--no-prune] [-o|--output-dir DIR] files ... DESCRIPTION
bootchart is used to process the log file created by bootchartd(1) (/var/log/bootchart.tgz by default). bootchart builds the process tree and renders a performance chart in different formats. The chart may then be analyzed to examine process dependency and overall resource utilization. OPTIONS
-f,--format FORMAT Sets the format of the image. Possible values are: png, eps, svg (default) -h, --help Display brief usage message. -n, --no-prune Do not prune the process tree. To make the resulting process tree more comprehensible, bootchart will prune the tree using various techniques (removing short-lived processes, merging processes, etc.). This option disables such behavior. -o, --output-dir DIR Sets the output directory for the resulting image. (default: .) -v, --version Show program version. FILES
/var/log/bootchart.tgz the default log file to parse (unless otherwise specified). SEE ALSO
bootchartd(1) AUTHOR
bootchart was written by Ziga Mahkovec <ziga.mahkovec@klika.si>. This manual page was written by Jorg Sommer <joerg@alea.gnuu.de>, for the Debian project (but may be used by others). 2006-03-05 BOOTCHART(1)
