Problem with string manipulation in bash
i have this code
Code:
#bin/bash
$SUB=":"
$REP=")"
if [ $# -eq 0 ]
then echo "please pass a filename as a an argument"
else
{
if [ -f $1 ]
then
{
$VAR | grep -n $USER $1; echo -n $VAR
$newVAR=${$VAR/$SUB/$REP}
}
fi
}
fi
i get error scriptname:line 2: = :: command not found and scriptname:line 3: =): command not found how do fix this. also how do i put the regular expression line so that it replaces all the colons in bigenning of all lines in $VAR instead of just the first one? (i am not allowed to use sed or awk for this exercise or a temp file) Last edited by u_hafeez : May 5th, 2008 at 07:49 PM.

Don't user $ at start of a variable assignmnemt, unless you intend to have the contents of the variable be the variable name being assigned to:
Code:
SUB=":" REP=")"
