The message is giving you a clue here. Is there any line in any file under /vob/project that contains a line longer than 2048 chars, which is a limit for some Unix commands?
Try this to count the length of lines in your files Code:
#!/bin/sh
for file in "$@"; do
echo -e "\nFILE: $file"
awk '{printf( "%5d: %s\n", length( $0 ), $0 ) }' $file
done
$ linelength /vob/project/* Cheers ZB

The script will post the length of all lines in all files, regardless of length. To find the lines longer than 2047 chars, try
Code:
#!/bin/sh
for file in "$@"; do
awk -v f=$file '{ if ( length( $0 ) > 2047 ) {
printf( "%s %5d: %s\n", f, length( $0 ), $0 );
}
}' $file
done
If you have a newer version of wc you can try wc -L /vob/project/* (captial L) to show the length of the longest line in each file. So, assuming your wc supports this, Code:
#!/bin/sh
MAX_LINE=2047
TEMPFILE=/tmp/out.$$.txt
# first, create temp file with list of files + max line lengths
find . -type f -print | xargs wc -L | grep -v total >> ${TEMPFILE}
while read term
do
while read line
do
max_line=$(echo $line | awk '{print $1}')
filename=$(echo $line | awk '{print $2}')
if [ "$max_line" -lt "$MAX_LINE" ]; then
echo "$filename:" >> ~/$term.txt
grep -i "$term" $filename >> ~/$term.txt
fi
done < ${TEMPFILE}
done < search.strings
rm -f ${TEMPFILE}
Cheers ZB
