Here is a short script/memo to find strings inside given file.
The script is assumed to be called strfind. It is written in bash.
Here is the spec of this script.
michael@boheme:~/bin $ strfind ?
Usage: strfind [-i] [filename] [string]
Exemple: strfind "[hc]" text
You can then find strings with commands like:
strfind *.c $TEXT_SEARCH
It is also possible to ignore case distinctions.
strfind -i *.c $TEXT_SEARCH
So here is the script.
#!/bin/bash
#Find string strings in select file extension
#Expected base arguments
EXPECTED_ARGS=2
IFLAG=0
while getopts 'i' OPTION
do
case $OPTION in
i) #Track in repo all untracked files
IFLAG=1
#+1 base argument
EXPECTED_ARGS=$(($EXPECTED_ARGS + 1))
;;
?) echo "Usage: `basename $0` [-i] [filename] [string]"
echo "Exemple: `basename $0` \"[hc]\" text"
exit 0
;;
esac
done
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: `basename $0` [-i] [filename] [string]"
echo "Exemple: `basename $0` \"[hc]\" text"
exit 1
fi
#Have only 2 or 3 arguments
if [ "$EXPECTED_ARGS" = "2" ]
then
FILENAME=$1
TXTSTRING=$2
else
FILENAME=$2
TXTSTRING=$3
fi
#Print file name and line number
OPTIONS="-Hn"
#Don't care about large characters
if [ "$IFLAG" = "1" ]
then
OPTIONS=$OPTIONS"i"
fi
#Execute command
echo find . -name "$FILENAME" -exec grep $OPTIONS $TXTSTRING {} \;
find . -name "$FILENAME" -exec grep $OPTIONS $TXTSTRING {} \;
exit 0;
