Need to create file from shell scripting

Shell Programming and Scripting
1

Hi,
I want to create a file from a shell script. the data for the file will come from variables. that is the file format is like,

var1-value var2_value ...

that is, var1_value should be placed in first 10 spaces and var2_value should be placed in next 8 columns like that.

is there any idea to do like this?

Thanks in advance,
Raja.

use "touch" to create files, or "echo", like :

touch /opt/file-${var}-more.txt
echo "" > /opt/file-${var}-more.txt
3

Or simply

> /opt/file-${var}-more.txt

Hi,

the 'printf' primitive allows you to assign or display a formatted string.

It can be used this way:
#-----------------------------------------------------
typeset LP_FILE=${HOME}/tmp/test.txt

# Variables for test
typeset VAR1_VALUE='12345678'
typeset VAR2_VALUE='ABCDEF'

# Remove the target file if any
rm -f ${LP_FILE}

# Dump the data values to the file
printf "%-10s" ${VAR1_VALUE} >> ${LP_FILE}
printf "%-8s" ${VAR2_VALUE} >> ${LP_FILE}
# Add '\n' if you want a newline character: printf "%-8s\n"

# Display the results
echo "*** [BEGIN] '${LP_FILE}' file content"
cat ${LP_FILE}
echo "*** [END] '${LP_FILE}' file content"
#-----------------------------------------------------

Hope it helps,
C.
