Aunque es una tonter\u00eda, hoy me volvi loco porque ten\u00eda que hacer un script en bash<\/strong> que parseara un archivo linea por linea<\/strong>. El problema que tenia era que cada linea tenia palabras y estas estaban separadas por espacios en blanco<\/strong>. Entonces al hacer un bucle for me pon\u00eda una palabra por linea, es decir si el archivo tenia este contenido:<\/p>\n

Esto es una linea
\nEsto es otra
\nY esta es la ultima<\/p>\n

for line in $(cat fichero_lineas.txt); do echo \u00ab$linea\u00bb ; done<\/p>\n

Esto
\nes
\nuna
\nlinea
\nEsto
\nes
\notra
\nY
\nesta
\nes
\nla
\nultima\n<\/p><\/blockquote>\n

Encontr\u00e9 dos soluciones<\/strong>: <\/p>\n

Una es usar un blucle while<\/strong> e ir leyendo l\u00ednea por l\u00ednea<\/strong> con read.<\/p>\n

#!\/bin\/bash<\/p>\n

while read linea; do
\n echo $linea
\ndone < $1<\/p><\/blockquote>\n

La otra es cambiar el valor de la variable IFS<\/strong>, que es el separador de campo. Por ejemplo IFS=’\\n’ que es el retorno de carro.<\/p>\n

IFS=’\\n’
\nfor i in $(cat $1)
\ndo
\n echo $i
\ndone<\/p><\/blockquote>\n
