ksh - read file with leading spaces

momi · #1 (**permalink**) 03-14-2008

Hi,

Could someone has any suggestions on this? When read a line from a file, I need to check the first char in the line, it could be a space or any char. But the leading spaces are removed by read.

Thanks.

See the following short example for one way of doing what you want.

Code:

#!/usr/bin/ksh93

TMP=file.$$

IFS=""
cat <<EOT >$TMP
  AAA BBB CCC
DDD EEE FFF
EOT

while read LINE
do
   echo $LINE
done < $TMP

rm $TMP

Thanks. Works by setting the IFS.
