Hello,
Could some one please tell what is the difference between
${1+"$@"} AND "$@"
I know "$@" is a string containing all the arguments to the script and I used to use it.
Recently, I found a script which use ${1+"$@"} and I am curious to know what is special with that & how it is working.
I did do some google before asking here, but I couldn't find a good resource explaining this.
Thanks in advance
