I am getting some data and putting that into a file with a sed command
awk '/name_of_the_person/{getline; print}' file_name | cut -d '>' -f 2 | cut -f 1 -d'<' |sed 's/^/export FIRST_NAME=/' >> /tmp/source
awk '/clan_of_the_person/{getline; print}' file_name | cut -d '>' -f 2 | cut -f 1 -d'<' |sed 's/^/export LAST_NAME=/' >> /tmp/source
and then I finally source this file to export the variables.
The problem that I am facing is that sometimes some people have multiple first names and last names and my file ends up like this
export FIRST_NAME=JEAN PAUL
export LAST_NAME=SMITH
This ends up breaking my export statement. Is there a way I can add quotes after the = till the end of the line so that it becomes
export FIRST_NAME="JEAN PAUL"
With GNU sed and a back-reference:
echo 'export FIRST_NAME=JEAN PAUL' | sed -E 's/=(.*)/="\1"/'
Output:
export FIRST_NAME="JEAN PAUL"
You could use a subshell to isolate the match. This has an added advantage of taking out the sed:
echo "export FIRST_NAME=\"$(awk '/name_of_the_person/{getline; print}' file_name | cut -d '>' -f 2 | cut -f 1 -d'<')\"" >> /tmp/source
echo "export LAST_NAME=\"$(awk '/clan_of_the_person/{getline; print}' file_name | cut -d '>' -f 2 | cut -f 1 -d'<')\"" >> /tmp/source
It might look cleaner with separate variables:
fname="$(awk '/name_of_the_person/{getline; print}' file_name | cut -d '>' -f 2 | cut -f 1 -d'<')"
lname="$(awk '/clan_of_the_person/{getline; print}' file_name | cut -d '>' -f 2 | cut -f 1 -d'<')"
{
echo "export FIRST_NAME=\"$fname\""
echo "export LAST_NAME=\"$lname\""
} >> /tmp/source

I'm extracting two md5sums by using this code:
md5sum test{1,2} | cut -d' ' -f1-2
I'm receiving two md5sums as in example below:
02eace9cb4b99519b49d50b3e44ecebc
d8e8fca2dc0f896fd7cb4cb0031ba249
Afterwards I'm not sure how to compare them. I have tried using the xargs:
md5sum test{1,2} | cut -d' ' -f1-2 | xargs bash -c '$0 == $1'
However, it tries to execute md5sum as a command
Any advice?
Try using a command subsitution instead
#!/bin/bash
echo 1 > file_a
echo 2 > file_b
echo 1 > file_c
file1=file_a
# try doing "file2=file_b" as well
file2=file_c
if [[ $(sha1sum $file1 | cut -d ' ' -f1-2) = $(sha1sum $file2 | cut -d ' ' -f1-2) ]]; then
echo same
else
echo different
fi
I need to read a json file and take value like 99XXXXXXXXXXXX0 and cccs and write in csv which having column BASE_No and Schedule.
Input file: classedFFDCD_5666_4888_45_2018_02112018012106.021.json
"bfgft":"99XXXXXXXXXXXX0","fp":"XXXXXX","cur_gt":225XXXXXXXX0,"cccs"
"bfgft":"21XXXXXXXXXXXX0","fp":"XXXXXX","cur_gt":225XXXXXXXX0,"nncs"
"bfgft":"56XXXXXXXXXXXX0","fp":"XXXXXX","cur_gt":225XXXXXXXX0,"fgbs"
"bfgft":"44XXXXXXXXXXXX0","fp":"XXXXXX","cur_gt":225XXXXXXXX0,"ddss"
"bfgft":"94XXXXXXXXXXXX0","fp":"XXXXXX","cur_gt":225XXXXXXXX0,"jjjs"
Expected output:
BASE_No,Schedule
99XXXXXXXXXXXX0,cccs
21XXXXXXXXXXXX0,nncs
56XXXXXXXXXXXX0,fgbs
44XXXXXXXXXXXX0,ddss
94XXXXXXXXXXXX0,jjjs
I am using below code for reading file name and date, but unable to read file for BASE_No,Schedule.
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
for line in `ls -lrt *.json`; do
date=$(echo $line |awk -F ' ' '{print $6" "$7}');
file=$(echo $line |awk -F ' ' '{print $9}');
echo ''$file','$(date "+%Y/%m/%d %H.%M.%S")'' >> $File_Tracker`
Assuming the structure of the json doesnt change for every line, the sample code checks through line by line to retrieve the particular value and concatenates using printf. The output is then stored as new output.txt file.
#!/bin/bash
input="/home/kj4458/winhome/Downloads/sample.json"
printf "Base,Schedule \n" > output.txt
while IFS= read -r var
do
printf "`echo "$var" | cut -d':' -f 2 | cut -d',' -f 1`,`echo "$var" | cut -d':' -f 4 | cut -d',' -f 2` \n" | sed 's/"//g' >> output.txt
done < "$input"
awk -F " \" " ' {print $4","$12 }' file
99XXXXXXXXXXXX0,cccs
21XXXXXXXXXXXX0,nncs
56XXXXXXXXXXXX0,fgbs
44XXXXXXXXXXXX0,ddss
94XXXXXXXXXXXX0,jjjs
I got that result!
I'm working on a shell script.
OUT=$1
here, the OUT variable is my filename.
I'm using grep search as follows:
l=`grep "$pattern " -A 15 $OUT | grep -w $i | awk '{print $8}'|tail -1 | tr '\n' ','`
The issue is that the filename parameter I must pass is test.log.However, I have the folder structure :
test.log
test.log.001
test.log.002
I would ideally like to pass the filename as test.log and would like it to search it in all log files.I know the usual way to do is by using test.log.* in command line, but I'm facing difficulty replicating the same in shell script.
My efforts:
var-$'.*'
l=`grep "$pattern " -A 15 $OUT$var | grep -w $i | awk '{print $8}'|tail -1 | tr '\n' ','`
However, I did not get the desired result.
Hopefully this will get you closer:
#!/bin/bash
for f in "${1}*"; do
grep "$pattern" -A15 "$f"
done | grep -w $i | awk 'END{print $8}'
i have a file /ws/$1-rcd/temp.txt which has only one line as follows
198|/vob/ccm_tpl/repository/open_source/commons_collections/3_2_2/...
i have a script to get the value repository/open_source/commons_collections and 3_2_2 by reading the file and looping through it using for loop
i have my code as follows
grep -n "$4" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f1,2 | sed -e 's/\:element/|/g' | sed -e 's/ //g' > /ws/$1-rcd/temp.txt
for i in `cat /ws/$1-rcd/temp.txt`
do
line=`echo $i | cut -d"|" -f1`
path=`echo $i | cut -d"|" -f2`
whoami
directory_temp=`echo $path | awk -F "/" '{ print $(NF-2)}'`
if [ "$directory_temp" == "$4" ]
then
OLD_VERSION=`sed -n "${line}p" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f2 | awk -F "/" '{ print $(NF-1)}'`
total_fields=`sed -n "${line}p" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f2 | awk -F "/" '{ print NF }'`
dir_path=`expr ${total_fields} - 2`
loc=`sed -n "${line}p" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f2 | cut -d"/" -f1-"${dir_path}"`
location=`echo $loc | cut -d"/" -f4,5,6`
fi
done
but when i run this code it gives me an error as
-bash: line 45: syntax error near unexpected token |'
-bash: line 45:for i in 198|/vob/ccm_tpl/repository/open_source/commons_collections/3_2_2/...'
can anyone please suggest what am i doing wrong
If you want to iterate through each line of a file, use while loop like below
while read -r line ;do
echo $line
done <file.txt
so, your code can be rewritten as
grep -n "$4" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f1,2 | sed -e 's/\:element/|/g' | sed -e 's/ //g' > /ws/$1-rcd/temp.txt
while read i ; do
line=`echo $i | cut -d"|" -f1`
path=`echo $i | cut -d"|" -f2`
whoami
directory_temp=`echo $path | awk -F "/" '{ print $(NF-2)}'`
if [ "$directory_temp" == "$4" ]
then
OLD_VERSION=`sed -n "${line}p" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f2 | awk -F "/" '{ print $(NF-1)}'`
total_fields=`sed -n "${line}p" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f2 | awk -F "/" '{ print NF }'`
dir_path=`expr ${total_fields} - 2`
loc=`sed -n "${line}p" /ws/$1-rcd/raw-vobs-config-spec | cut -d " " -f2 | cut -d"/" -f1-"${dir_path}"`
location=`echo $loc | cut -d"/" -f4,5,6`
fi
done < /ws/$1-rcd/temp.txt
You may be better served relying on parameter expansion and substring removal. For example:
#!/bin/sh
a=$(<dat/lline.txt) ## read file into a
a=${a##*ccm_tpl/} ## remove from left to ccm_tpl/
num=${a##*collections/} ## remove from left to collections/
num=${num%%/*} ## remove from right to /
a=${a%%${num}*} ## remove from right to $num
Input File
$ cat dat/lline.txt
198|/vob/ccm_tpl/repository/open_source/commons_collections/3_2_2/..
Output
$ sh getvals.sh
a : repository/open_source/commons_collections/
num : 3_2_2
If you need to trim in some other way, just let me know and I'm happy to help further.
I need some help . I want the result will be
UP:N%:N%
but the current result is
UP:N%
:N%
this is the code.
#!/bin/bash
UP=$(pgrep mysql | wc -l);
if [ "$UP" -ne 1 ];
then
echo -n "DOWN"
else
echo -n "UP:"
fi
df -hl | grep 'sda1' | awk ' {percent+=$5;} END{print percent"%"}'| column -t && echo -n ":"
top -bn2 | grep "Cpu(s)" | \sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | \awk 'END{print 100 - $1"%"}'
You can use command substitution in your first sentence (notice you're creating a subshell in this way):
echo -n $(df -hl | grep 'sda1' | awk ' {percent+=$5;} END{print percent"%"}'| column -t ):
