I am using the following script to get the start numbers from the output. Which is working fine as shown below with multiple lines of script.
openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1 > outfile.txt
startnum=$(cat outfile.txt | cut -f1 -d:)
echo "startnum:$startnum"
contents of outfile.txt:
7430:d=7 hl=2 l= 11 prim: OBJECT :id-smime-aa-pattern
7567:d=7 hl=4 l=5216 cons: SET
OUTPUT:
startnum: 7430
7567
But I would like achieve that in single line which i have tried in several ways, but could not do. Any pointers/help appreciated.
startnum=$(cat $(openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1) | cut -f1 -d:)
startnum=$(`cat $(openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1)` | cut -f1 -d:)
startnum=$(cat $(`openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1 | grep id-smime-aa-pattern -A 1`) | cut -f1 -d:)
startnum=$(cat (`openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1 | grep id-smime-aa-pattern -A 1`) | cut -f1 -d:)
startnum=$(cat `openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1 | grep id-smime-aa-pattern -A 1` | cut -f1 -d:)
startnum=$(`openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1 | grep id-smime-aa-pattern -A 1` | cut -f1 -d:)
startnum=$($(`openssl asn1parse -inform der -in $1 | grep id-smime-aa-pattern -A 1 | grep id-smime-aa-pattern -A 1`) | cut -f1 -d:)
