Search Results

Breaking down the result line again will work:

result=`grep -n "${id}" getCSV.txt`
if [ -n "$result" ]; then
echo "match found in line $result"|sed 's/:.*//'
echo "$result"|sed 's/[^:]*://'...

Using the -n option to grep will do the trick:


printf "searching, please wait"
result=`grep -n "${id}" getCSV.txt`
if [ -n "$result" ]; then
echo "match found in line $result" >>...

Your read loop doesn't seem to read from the downloaded file. Anyway I wouldn't try to emulate grep with shell commands. Instead the loop could be replaced by the use of
grep "${id}" getCSV.txt. For...

The following awk command will do that:
awk -F ">" '/Last Contact>.* d/ { if ($2 >= 2) print }' test.csv

That is, consider only lines measured in days - this scheme will fail if you encounter...

Does your C++ service change its uid at some point? Because core file generation is disabled by default for security reasons in that case; writing the value 2 to /proc/sys/fs/suid_dumpable will help...

If you save that and view it with xdd/od -x, does it come up as 2e ? If it saves as two bytes instead, it is a font problem.

You will need to make sure that your terminal/editor uses an utf8 locale. The locale command will show your settings and specifically you want to set LC_CTYPE to an utf8 locale (for example...

You will need to put the condition into parenthesis:

if ((!($InputLine=~/^Date/)) && ($fields[6] eq "VEN")) {

This is probably the difference between line buffering on the shell, and block buffering when the result is piped. To test the theory, just pipe the find through cat in the shell. It will probably...

This depends a bit on the version of the date command available on your system. But you could use it to find the month for the day before yesterday.
total_days=`cal $(date -d "-2 days" "+%m %Y") |...

Ok, so where does the No file found message come from? Sounds like it would be find (linux find doesn't do this btw.). Or isn't that the exact error message?

I see.

Strangely trying your example as is works for me. Are you using a different shell for the script than on the command line? In any case doing something like bash -x scriptname may help with...

Alphabetical sorting will sort the newest last, so something like this will work:

sort input.txt|head -n -1|while read file; do rm "$file"; done
Of course if you generate the list via ls ...

The last line should probably read done > searchstring.out, that is redirecting the output.

Screen is probably what you are looking for: https://www.unix.com/man-page/redhat/1/screen/ (https://www.unix.com/man-page/redhat/1/screen/)

You can replace multiple words with:
sed -E 's/(word1|word2|word3)/,/g'Your sed version might support case insensitive matching:
sed -E 's/(word1|word2|word3)/,/gI'Depending on how your list looks...

Busybox uses its own implementation of awk, seemingly one that uses null-terminated strings internally (as opposed to length prefixed, which could handle null characters inside strings). I used...

Busybox awk seems to be unable to output null characters, this breaks your complex example.

You can find a bit about it in the second answer's comments here:

I'm not sure what you want to achieve. If you want the the link to point to a new file, removing it and creating a new link will do that:


rm VEUEMASTER.txt
ln -s /sbvnj/kfls/OTHER_FILE...

Hm, works for me:


$ f="ABCD_1234_20150324_A02415453.PDF"
$ echo $f|cut -d'_' -f2 | ( read ID2; echo mv $f $(echo $f | sed "s/\(_2015.*\)_.*.PDF/\1_X01$ID2.PDF/") )
mv...

ID2 will be set in the wrong subshell and single quotes will prevent variable substitution. The following should work:


echo $f |cut -d'_' -f2 | ( read ID2; mv $f $(echo $f | sed...

Separating the substitutions works:

awk 'NR>1 { if ($2 ~ /^\(/ ) {$1=""; print "Found error: ", $0} else { sub(/.*:/, "", $1); sub(/.*:/, "", $7); print "No error: " $1 "," $7}}'...

Something like the following should work then:

awk 'NR>1 { if ($2 ~ /^\(/ ) {$1=""; print "Found error: ", $0} else { sub(/.*:/, "", $1); print "No error: " $1 }}'...

It is not clear to me how to distinguish the error case from the case with no errors. In sample1 we have (variantchecker): in the second column, in sample2 it is NM_004004.5 GJB2_v001.

Can we...

This looks a lot like debug messages from ssh - those that appear if a few -v options are given upon connection.
