I have a test file called testPage with the following text:
|| '''Title1''' || '''Title2''' || '''Title3''' || || Cell11 || Cell12 || Cell13 || || Cell21 || Cell22 || || Cell31 || Cell32 || || Cell41 || Cell42 || || CEll51 || Cell52 || || Cell61 || Cell62 || || Cell71 || Cell72 ||
That I want to look like:
{|
|'''Title1''' || '''Title2''' || '''Title3''' ||
|-
| Cell11 || Cell12 || Cell13 ||
|-
| Cell21 || Cell22 ||
|-
| Cell31 || Cell32 ||
|-
| Cell41 || Cell42 ||
|-
| CEll51 || Cell52 ||
|-
| Cell61 || Cell62 ||
|-
| Cell71 || Cell72
|}
I have a script:
#!/bin/bash
isTable=0
beginTable="^||"
lineNum=1
while IFS= read -r line
do
echo "lineNum: $lineNum, line: $line, isTable: $isTable"
if [[ $line =~ $beginTable ]]
then
if [ "$isTable" -eq "0" ]
then
isTable=1
sed -r $lineNum's_||_{|n|_' -i testPage #Begin table
echo "begin table"
else
sed -r $lineNum's_^||_|-n|_' -i testPage #Define row ##DOESN'T WORK##
echo "start of row"
fi
else
if [ "$isTable" -eq "1" ]
then
isTable=0
sed -r $lineNum's_(.*)$_1n|}n_' -i testPage #End table ##WEIRD RESULT##
echo "end table"
fi
fi
((lineNum++))
done < testPage
That gives the result:
{|
| '''Title1''' || '''Title2''' || '''Title3''' ||
|-
| Cell11 || Cell12 || Cell13 ||
|-
| Cell21 || Cell22 ||
|-
| Cell31 || Cell32 ||
|| Cell41 || Cell42 ||
|}
|| CEll51 || Cell52 ||
|| Cell61 || Cell62 ||
|| Cell71 || Cell72 ||
I can’t figure out why it stops substituting after three iterations even though the loop reports the appropriate line and line number as well as matching the appropriate logic.
Any help is appreciated.
For clarity, testPage is a portion of a larger file, so sed beginning and ending flags (i.e., doing different things on lines 1 and $)
won’t do for me.
Answer
I used a combination answers to achieve my desired result.
#!/bin/bash
isTable=0
beginTable="^||"
lineNum=1
tableCount=0
while IFS= read -r line #Print changes to temp file
do
if [[ $line =~ $beginTable ]]
then
if [ "$isTable" -eq "0" ]
then
isTable=1
((tableCount++))
> $1_$tableCount
sed -n -r $lineNum's_^||_{|n|_p' $1 >> $1_$tableCount #Begin table
sed -r $lineNum's_^||_@'$tableCount'@_' -i $1
else
sed -n -r $lineNum's_^||_|-n|_p' $1 >> $1_$tableCount #Define row
fi
else
if [ "$isTable" -eq "1" ]
then
isTable=0
sed -n -r $lineNum's_(.*)$_1|}n_p' $1 >> $1_$tableCount #End table
fi
fi
((lineNum++))
done < $1
for ((n=1;n<=$tableCount;n++))
do
sed -e '/@'$n'@/r '$1'_'$n'' -e '/^@'$n'@/d;/^||/d' -i $1
rm "$1"_"$n"
done
I print each table to a different numbered file and then sed read each of those into the original file.
