say I have a file named phones
in that file every line is like that
lastname^firstname^phone
how can I make a program in cshell that searches for a specific string
in phones and echos the result (if found) like that:
lastname1
firstname1
phone1
------------------
lastname2
firstname2
phone2
and so on....
I only know grep and it prints
lastname1^firstname1^phone1
lastname2^firstname2^phone2
...well thank you anyway

grep NAME | tr '^' '\n'
cfajohnsom thank you it works!(but I am sure you already know that :p)
you're the best!
how can I get the line "-------------------------"
to show between the results? thanks in advance!
#!/bin/bash
i=1
for a in `cat namelist`
do
echo "Loop$i:"
echo "+++++++"
grep $a testfile | tr '^' '\n'
echo "----------------------------"
i=`expr $i + 1`
done
"namelist" will contain all the names that needs to be searched/formatted.
"testfile" is the file name
awk -F: -v srch="$1" '
BEGIN { OFS = "\n"; ORS = "\n------------------\n" }
index($0,srch) { $1 = $1; print }' "$FILE"
Please put code inside
tags.
#!/bin/bash
i=1
for a in `cat namelist`

That may work if there are no spaces in the file; it will definitely fail if there are.
To read a file line by line:
while IFS= read -r line
do
: whatever
done < FILENAME
That will fail if there's a space in the search term, and grep and tr are both unnecessary.
case $line in
*"$a"*) set -f; printf "%s\n" ${line//^/$'\n'} "---------------" ;;
esac
There is no need to use an external command to do integer arithmetic in any POSIX shell:
i=$(( $i + 1 ))
I don't understand how someof the above work...
can't I doanything abou that code
#!/bin/csh
if($#argv == 0)then
echo "usage is find <something>"
exit(1)
else
echo "USERS"
echo "----------------------------"
echo "Search for: $* "
foreach k ($*)
echo "----------------------------"
grep -i $k phones | tr '^' '\n'
if($status != 0)then
echo not found
else
echo "----------------------------"
endif
end
exit(0)
endif
that I completely understand how it works,
to make the "--------------------" line to appear between results?
I also tried to use awk before I posted my question here,but couldn't get it right(and still can't:confused:)
In a real scripting shell (i.e., not csh), that would be:
if [ $# -eq 0 ]
then
echo "usage is find <something>"
exit 1
fi
echo "USERS"
echo "----------------------------"
echo "Search for: $* "
for k in "$@"
do
echo "----------------------------"
result=$( grep -i "$k" phones | tr '^' '\n' )
if [ -z "$result" ]
then
echo not found
else
printf "%s\n" "$result" "----------------------------"
fi
done
Do yourself a favour and stop scripting in csh.
