This bash script extracts a random line from a given (text) file. This is a cheap "fortune" replacement. Goes well with a funny quotes file in you .bashrc :)
CODE:
-
#!/bin/bash
-
-
# randomline : extracts a random line from a text file
-
# Ozh, ozh@planetquake.com
-
-
if [ -z $1 ] ; then
-
echo "Usage : $0 <file>"
-
exit 0
-
fi
-
-
NB_LINES=$(expr $(wc -l $1 | sed -e 's/ *//' | cut -f1 -d " "))
-
-
NB_RAND=0
-
while [ "$NB_RAND" -eq 0 ]
-
do
-
NB_RAND=$(expr $RANDOM \% $NB_LINES)
-
done
-
-
sed -n "${NB_RAND}p;${NB_RAND}q" $1
